b933f9cf0c
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. Signed-off-by: Ian Cooper <iancooper@hotmail.com>
