Partial revert of "Remove obsolete __stack_chk_fail_local."

These sources are going to be used for the NDK as well, and the NDK
still uses GCC.

This partially reverts commit
4af220cf. That commit also removed
this symbol from the linker's crtbegin (it has its own). That is
still only built with Clang, so we don't need to revert that part.
