kevans f6e2de4a71 Provide libssp based on libc
For libssp.so, rebuild stack_protector.c with FORTIFY_SOURCE stubs that just
abort built into it.

For libssp_nonshared.a, steal stack_protector_compat.c from
^/lib/libc/secure and massage it to maintain that __stack_chk_fail_local
is a hidden symbol.

libssp is now built unconditionally regardless of {WITH,WITHOUT}_SSP in the
build environment, and the gcclibs version has been disconnected from the
build in favor of this one.
