Ian Cooper b933f9cf0c toolchain: remove gcc libssp and use libc variant
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.
