001f9a7988 Introduce the variable BR2_TOOLCHAIN_HAS_UCONTEXT
It is set when the platform exposes the struct ucontext_t.

This avoids duplication of logic inside each package requiring
the use of that type.

311af5e8c2 toolchain/toolchain-buildroot: enable glibc for all little-endian ARCs with atomic ops
Initially we had a port only for ARCv2 cores but then with a simple
change ARCompact cores got supported as well.

So we generalize from BR2_archs to BR2_arcle as we haven't tried to
get glibc working on big-endian ARCs yet.

Also we never bothered to check avaialbility of atomic instructions in
the core but in case of Glibc for ARC this is really a must, so we add
this check here.

Note in case of uClibc we may have system w/o HW atomics but:

 1. Only single-core systems are allowed
 2. Atomic instructions are emulated via arc_usr_cmpxchg syscall

a181d5de36 toolchain: move glibc nsswitch.conf handling to a post-target hook
nsswitch.conf is processed both by the toolchain, nss-mdns and
nss-myhostname without any guaranteed ordering in between.

The toolchain package ensures that nsswitch.conf is available, and the two
nss-* packages tweaks the content, so the toolchain processing should run
before the nss-* ones.  Toolchain is a dependency of all the packages, so
ensure this is done by moving the toolchain handling to a
post-target-install hook.

Also move the variable to toolchain/toolchain/toolchain.mk where the virtual
toolchain package is defined for clarity.

7484c1c3b8 toolchain/toolchain-wrapper: add BR2_RELRO_
The RELRO/PIE flags are currently passed via CFLAGS/LDFLAGS and this patch
proposes moving them to the toolchain wrapper.

 (1) The flags should _always_ be passed, without leaving the possibility
     for any package to ignore them. I.e, when BR2_RELRO_FULL=y is used
     in a build, all executables should be built PIE. Passing those
     options through the wrapper ensures they are used during the build
     of all packages.

 (2) Some options are incompatible with -fPIE. For example, when
     building object files for a shared libraries, -fPIC is used, and
     -fPIE shouldn't be used in combination with -fPIE. Similarly, -r
     or -static are directly incompatible as they are different link
     time behaviors then the intent of PIE. Passing those options
     through the wrapper allows to add some "smart" logic to only pass
     -fPIE/-pie when relevant.

 (3) Some toolchain, kernel and bootloader packages may want to
     explicitly disable PIE in a build where the rest of the userspace
     has intentionally enabled it. The wrapper provides an option
     to key on the -fno-pie/-no-pie and bypass the appending of RELRO
     flags.
     The current Kernel and U-boot source trees include this option.
     8438ee76b0
     6ace36e19a
     If using PIE with a older Kernel and/or U-boot version, a backport of these
     changes  might be required. However this patchset also uses the
     __KERNEL__ and __UBOOT__ defines as a way to disable PIE.

NOTE: The current implementation via CFLAGS/LDFLAGS has caused some
build time failures as the conditional logic doesn't yet exist in
Buildroot:

d67cebcda0 toolchain: improve musl check to support static toolchains
The check_musl function currently builds a program and verifies if the
program interpreter starts with /lib/ld-musl. While this works fine
for dynamically linked programs, this obviously doesn't work for a
purely static musl toolchain such as [1].

There is no easy way to identify a toolchain as using the musl C
library. For glibc, dynamic linking is always supported, so we look at
the dynamic linker name. For uClibc, there is a distinctive
uClibc_config.h header file. There is no such distinctive feature in
musl.

We end up resorting to looking for the string MUSL_LOCPATH, which is
used by musl locale_map.c source file. This string has been present in
musl since 2014. It certainly isn't a very stable or convincing
solution to identify the C library as being musl, but it's the best we
could find.

Note that we are sure there is a libc.a file, because the
check_unusable_toolchain function checks that there is a such a file.

928c9289d2 toolchain-external-custom: allow specifying relative path to binaries
There are cases where a downloaded toolchain doesn't have its binaries
placed directly in a "bin" subfolder (where BuildRoot currently looks
for them).

A common example is the official Raspberry Pi Toolchain
(https://github.com/raspberrypi/tools), which has its binaries in
"arm-bcm2708/arm-linux-gnueabihf/bin".

This commit introduces BR2_TOOLCHAIN_EXTERNAL_REL_BIN_PATH that defaults
to "bin" and can be changed as needed.

5e58509bfe toolchain-wrapper: use -ffp-contract=off on MIPS Xburst for gcc >= 4.6
Since gcc 4.6, GCC deprecated -mfused-madd, -ffp-contract=off should
be used for the Xburst workaround.

Tested with the MIPS Sourcery 2011.03 toolchain (based on gcc 4.5),
the toolchain wrapper uses -mno-fused-madd, as expected:

$ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c
Toolchain wrapper executing:
    '/home/thomas/toolchains/mips-2011.03/bin/mips-linux-gnu-gcc'
    '--sysroot'
    '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot'
    '-mabi=32'
    '-msoft-float'
    '-mno-fused-madd'
    '-EL'
    '-march=mips32r2'
    '-o'
    'toto'
    'toto.c'

And with the MIPS Sourcery 2012.09 toolchain (based on gcc 4.7), the
toolchain wrapper uses -ffp-contract=off, as expected:

$ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c
Toolchain wrapper executing:
    '/home/thomas/toolchains/mips-2012.09/bin/mips-linux-gnu-gcc'
    '--sysroot'
    '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot'
    '-mabi=32'
    '-msoft-float'
    '-ffp-contract=off'
    '-EL'
    '-march=mips32r2'
    '-o'
    'toto'
    'toto.c'
