2e6f417d7e toolchain/external: copy libssp.so if SSP is enabled
In Buildroot, the internal toolchain backend uses the SSP support from
the C library, not that of gcc.

Some external toolchains come with SSP suport in gcc, which is
implemented in libssp.so, rather than in the C library.

When a toolchain even has both, it is up to the compiler to decide
whether it will link to libssp or use the support from the C library.

However, in the latter case, a (incorrectly written) package may decide
to explicitly link with libssp.so when it is available (even though the
compiler may have decided otherwise if left by itself). This is the case
for example with sox, which results in runtime failures, such as:

    $ sox
    sox: error while loading shared libraries: libssp.so.0: cannot open
    shared object file: No such file or directory

Even if sox is wrong in doing so, the case for libssp-only toolchains is
still valid, and we must copy it as we copy other libs.

GCC hangs while building brotli for the Microblaze Arch:

31a1dec1f5 toolchain: generate check-headers program under $(BUILD_DIR)
Some installations mount /tmp with the 'noexec' option, which prevents
running the program generated there to check the kernel headers.

Avoid the problem by generating the program under $(BUILD_DIR), passed
as the first argument to check-kernel-headers.sh.

We could globally export a TMPDIR environment variable with some path
under $(BUILD_DIR) but such solution would be too intrusive, depriving
the user from the freedom to set TMPDIR at his will (or needs).

306f507f9d toolchain: add variadic MI thunk support flag
GCC uses thunk functions to adjust the 'this' pointer when calling C++
member functions in classes derived with multiple inheritance.
Generation of thunk functions requires support from the compiler back
end. In the absence of that support target-independent code in the C++
front end is used to generate thunk functions, but it does not support
vararg functions.

Support for this feature is currently missing in or1k and xtensa
toolchains.

Add hidden option BR2_TOOLCHAIN_SUPPORTS_VARIADIC_MI_THUNK that
indicates presence of this feature in the toolchain. Add dependency to
packages that require this feature to be built.

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.

Add BR2_TOOLCHAIN_SUPPORTS_ALWAYS_LOCKFREE_ATOMIC_INTS variable and
use it in BR2_TOOLCHAIN_HAS_GCC_BUG_64735.

This new variable will be used to select boost atomic when lock-free

fd97bc80c5 toolchain: allow disabling packages affected by gcc bug 85180
Works around https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180 which
is an issue where the Microblaze architecture had code that caused a
infinite recursion while optimizing in versions of GCC earlier than
8.x. More BR discussion can be found on this thread.
