commit: http://git.buildroot.net/buildroot/commit/?id=a2cc96556e4ce910b397181c222a116ebf04465d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Now that we are always explicitly passing gcc_cv_libc_provides_ssp,
there is no longer any reason to modify the gcc configure/configure.ac
to take into account the musl case. When a musl toolchain is being
built, BR2_TOOLCHAIN_HAS_SSP is always 'y', and therefore
gcc_cv_libc_provides_ssp=yes is always passed when building
gcc-initial and gcc-final.
