bf82deff70 build: disable kernel stack protector support for i386/x86_64
When stack protector support is disabled in libc (always the case for
!musl), gcc assumes that it needs to use __stack_chk_guard for the stack
canary.
This causes kernel build errors, because the kernel is only set up to
handle TLS stack canaries.

1877bc9d8f gcc/musl: rework SSP-support
Make musl provide libssp_nonshared.a and make GCC link it unconditionally
if musl is used. This should be a no-op if SSP is disabled and seems to be
the only reliable way of dealing with SSP over all packages due to the mess
that is linkerflags handling in packages.

491f3fc048 Support for building an hardened OpenWRT
Introduce configuration options to build an "hardened" OpenWRT.

Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO
have been introduced.

uClibc makefile now automatically detects if SSP support is necessary.

hostapd makefile has been fixed to use "^" as sed separator since
using a comma was problematic when using "-Wl,-z,now" and the like in
TARGET_CFLAGS.

Currently enabling SSP on user space depends on enabling SSP kernel
side, this is due to the fact that TARGET_CFLAGS are used to build
kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice
entries.

Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of
the available packages.
Needs to be tested with GCC 4.9 and the remaining packages.
PIE not currently included.

7a1f4c50fa PKG_CHECK_FORMAT_SECURITY: add a menuconfig option, disable by default
The idea is still to enable it by default at some point
I've tested all ar71xx packages (except oldpackages) using CONFIG_ALL=y
Failing packages have been marked with PKG_CHECK_FORMAT_SECURITY:=0 for now
I can test more targets but i have no idea which are the most used
