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.

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.

Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).
Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.
While at it, make musl the default C library for external toolchain to match
the internal toolchain.
