libc: Define __atomic_is_lock_free.

Limited to architectures where it is actually needed by gcc for any
calls to stdatomic.h atomic_is_lock_free for now.

We should also add it to other architectures too, along with lockful
atomic r/m/w operations for sizes that can't be handled natively, but
that's a lot more work.  It is also necessary for -fno-inline-atomics
but we're missing a lot of other symbols for that too, to be fixed.

For now, this should enable the OpenSSL build to complete on these
architectures again after I reverted a local change.
