294e908a2c cmake: skip build system check on compile
cmake checks the build system and its variables on its own to detect if
the makefiles need to be regenerated.
Unfortunately this can invalidate overrides passed in the
Build/Configure step. On non-Linux systems this breaks the build when
switching between targets of the same package architecture.

Fix this by forcibly disabling the build system check and relying on the
LEDE build system to take care of these things

build: move STAGING_DIR_HOSTPKG and BUILD_DIR_HOST back to a common directory for all targets
Using a single host package staging dir (and build dir) significantly speeds up
builds when multiple targets are built in succession, especially for large host
packages like NodeJS.

$(STAGING_DIR)/host is kept in addition to $(STAGING_DIR_HOSTPKG) in most
places; it is still used as destination for host files in Build/InstallDev.

559fb537d8 build: use CXXFLAGS if defined
Instead of using TARGET_CFLAGS and EXTRA_CFLAGS in cmake and scons
build use the TARGET_CXXFLAGS and EXTRA_CXXFLAGS like it is done for
normal make and configure. configure used TARGET_CXXFLAGS and
EXTRA_CFLAGS for the CXXFLAGS. The package-default.mk sets
"EXTRA_CXXFLAGS = $(EXTRA_CFLAGS)" so using EXTRA_CXXFLAGS flags should
be save.

eadf5fb7f8 cmake: include/cmake.mk add CMAKE_BINARY_SUBDIR to allow out of source tree builds
Some packages need out of source tree building with cmake, for example
when building kernel modules.

a5422864f5 build: fix CMake assembly builds with ccache
CMAKE_ASM_COMPILER is automatically set to CMAKE_C_COMPILER by CMake, but
CMAKE_C_COMPILER_ARG1 is lost. This causes assembly builds to fail when ccache
is enabled (for example the package fastd on x86).

Fix this by explicitly defining CMAKE_ASM_COMPILER and CMAKE_ASM_COMPILER_ARG1.

9a46799804 build: use gcc-provided ar, nm and ranlib where appropriate
Since GCC 4.7, GCC provides its own wrappers around ar, nm and ranlib, which
should be used for builds with link-time optimization. Since GCC 4.9, using them
actually necessary for LTO builds using convenience libraries to succeed.

There are some packages which try to automatically detect if gcc-{ar,nm,ranlib}
exist (one example is my package "fastd" in the package repository, which tries
to use LTO). This breaks because the OpenWrt build system explicitly sets the
binutils versions of these tools.

As it doesn't cause any issues to use gcc-{ar,nm,ranlib} instead of
{ar,nm,ranlib} even without LTO, this patch just makes OpenWrt use the
GCC-provided versions by default, which fixes the build of such packages with
GCC 4.9.

(I know that builds fail though when clang is used with -flto and
gcc-{ar,nm,ranlib}, but as all OpenWrt toolchains are based on GCC, this isn't
a real issue.)

Completely cleaning the tree (or at least `make clean toolchain/clean`) is
necessary to get a consistent state after the binutils plugins support patch and
this one (as trying to use gcc-{ar,nm,ranlib} with a binutils built without
plugin support will definitely lead to a build failure).
