Removes the standalone implementation of stack smashing protection
in gcc's libssp in favour of the native implementation available
in glibc and uclibc. Musl libc already uses its native ssp, so this
patch does not affect musl-based toolchains.
Stack smashing protection configuration options are now uniform
across all supported libc variants.
This also makes kernel-level stack smashing protection available
for x86_64 and i386 builds using non-musl libc.

To prevent "wrong" musl packages which have a new version number
but the package still contains an old version, because
PKG_SOURCE_VERSION was unchanged.

This updates glibc to the most recent version 2.31.
001-regex-read-overrun.patch was a backport from a more recent version
and is integrated in glibc 2.31.
050-Revert-Disallow-use-of-DES-encryption-functions-in-n.patch is needed
to add the DES crypto functions back again. They were removed in glibc
2.28, but we still use them in ppp.
musl lib also provides these DES crypto functions. Without them we would
have to link ppp against openssl or an other crypto library.

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.
