musl libc through 1.1.23 has an x87 floating-point stack adjustment
imbalance, related to the math/i386/ directory. In some cases, use of
this library could introduce out-of-bounds writes that are not present
in an application's source code.
This problem only affects x86 and no other architectures.

This happens only the second time a library is loaded by dlopen().
After lib1 is loaded, dlsym(lib1,"undef1") correctly resolves the undef
symbol from lib1 dependencies. After the second library is loaded,
dlsym(lib2,"undef1") was returning the address of "undef1" in lib2
instead of searching lib2 dependencies.
Using upstream fix which now uses the same logic for relocation time
and dlsym.

GCC needs the kernel headers to compile.
Some GCC file includes asm/unistd.h which is provided by the kernel headers.
Normally the kernel headers build is very fast and ready before the gcc uses
it, but if it clones the kernel from a slow git repository it takes longer
and then it could be that the gcc already wants to use the kernel headers
before they are available. This patch fixes this problem by adding the
missing dependency.

This problem exposed when compiling glibc, but applicable across the
board. gcc compiles runtime libraries for all supported architectures,
unless otherwise specified, and later selects applicable library based
-m[arch,cpu,*] options, thus these options should not be passed to gcc

[modified so it only touches ARM - I'm too chicken, changed authors email]
Set the toolchain's ARM CPU and FPU architectures by utilizing' gcc's
--with-cpu / --with-fpu configure options that: "Specify which cpu
variant the compiler should generate code for by default. cpu will
be used as the default value of the -mcpu= switch."
This will resolve the following kernel compilation failures under
gcc 8.x on ARM because the kernel wants to set (possibly conflicting)
optimization flags.
.../ccyVnmrs.s:204: Error: selected processor does not support `dmb ish' in ARM mode
.../ccyVnmrs.s:215: Error: architectural extension `mp' is not allowed for the current base architecture
.../ccyVnmrs.s:216: Error: selected processor does not support `pldw [r4]' in ARM mode
Because this is a big change, the .config and toolchain need to be
refreshed (as in removed and regenerated).

"This release makes improvements with respect to default thread stack
size, including increasing the default from 80k to 128k, increasing
the default guard size from 4k to 8k, and allowing the default to be
increased via ELF headers so that programs that need larger stacks can
be build without source-level changes, using just LDFLAGS.
Insufficient stack size for AIO threads on kernels that don't honor
the constant MINSIGSTKSZ is also fixed.
The glob core has been rewritten to fix inability to see past
searchable-but-unreadable path components, and to avoid excessive
stack usage and unnecessary syscalls. The tsearch AVL tree
implementation has also been rewritten for better size and
performance. The math library adds more native single-instruction
implementations for arm, s390x, powerpc, and x86_64.
Various bugs are fixed, including several possible deadlocks, one of
which was a new regression in 1.1.20."

Instead of silently downgrading any non-MD5 crypt() request to DES,
cleanly fail with return NULL and errno = ENOSYS. This allows callers
to notice the missing support instead of the unwanted silent fallback
to DES.
Also add a menuconfig toolchain option to optionally disable the crypt
size hack completely. This can be probably made dependant on SMALL_FLASH
or a similar feature indicator in a future commit.

This release introduces the ability to replace/interpose the allocator
(malloc) subject to certain restrictions, adds an experimental m68k
port, and makes notable improvements to stdio (application-provided
buffers), getaddrinfo (AI_ADDRCONFIG, support for IPv4-only kernel
configurations), the dynamic linker (safety against dlopen of
libraries using initial-exec TLS model, reclaiming unused memory on
FDPIC archs, better dladdr results), and handling of default thread
stack size (pthread_setattr_default_np now works more reliably).
Many bugs have been fixed, including potentially dangerous regressions
in iconv (only for new conversions to legacy encodings) and visibly
incorrect behavior in printf on non-x86 archs (%a format with
precision specifier), in getopt_long_only when short options are a
prefix for a long option, in complex arc-trig/hyperbolic functions, in
strftime and mktime (timezone-specific issues), and numerous
less-obvious places.

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.

GCC supports starting version 5 --enable-default-ssp and starting version 6
--enable-default-pie.

compilation flags.

When using an external git clone for the kernel repo,
the build would fail because the build won't download
[via git] the kernel tarball.
This is because the `toolchain/kernel-headers` assumes
that the kernel would get downloaded via normal HTTP.
The reason for this is the `HostBuild` rule, which
calls the `Download/default` rule.
To use the `Download/default` we just need to conditionally
adjust some PKG_ vars.
We can safely use `LINUX_VERSION` as it was already adjusted
in the `kernel-version.mk` to avoid collisions with other tarballs.

Currently on attempt to configure uClibc with "V=s" user is prompted
to answer on configuration questions. Major inconvenience here is
build procedure get paused until user answers all questions.
That happens because not all symbols are defined in our .config.
Solution is as simple as usage of "olddefconfig" target instead of
simple "oldconfig". In that case default values get silently set
for symbols not defined by our .config explicitly.
We haven't noticed that subtle issue before because without "V=s"
what we do is "make oldconfig < /dev/null" which automatically
answers all questions :)

Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).
Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.
While at it, make musl the default C library for external toolchain to match
