Rework handling of asynchronous unwind tables compiler flag 

This commit drops an overridden -fasynchronous-unwind-tables flag, which
had no effect.

We compile all of glibc with -fno-asynchronous-unwind-tables, so we can
drop glibc-fedora-ppc-unwind.patch.

* Thu Nov 30 2006 Jakub Jelinek <jakub@redhat.com> 2.5.90-9
- on ppc64 build __libc_start_main without unwind info,
as it breaks MD_FROB_UPDATE_CONTEXT (#217729, #217775; in the
future that could be fixable just by providing .cfi_undefined r2
in __libc_start_main instead)
