On some systems executable stacks are denied. Since libunwind and the
tests don't actually need executable stacks this patch marks all
assembly files as not needing it.

The original patch comes from frysk:

2007-04-05  Jan Kratochvil  <jan.kratochvil@redhat.com>

    * src/hppa/getcontext.S, src/hppa/setcontext.S, src/hppa/siglongjmp.S,
    src/ia64/Ginstall_cursor.S, src/ia64/Linstall_cursor.S,
    src/ia64/dyn_info_list.S, src/ia64/getcontext.S, src/ia64/longjmp.S,
    src/ia64/setjmp.S, src/ia64/siglongjmp.S, src/ia64/sigsetjmp.S,
    src/ppc64/longjmp.S, src/ppc64/siglongjmp.S, src/x86/longjmp.S,
    src/x86/siglongjmp.S, src/x86_64/longjmp.S, src/x86_64/setcontext.S,
    src/x86_64/siglongjmp.S: Stack should be non-executable, for SELinux.

I added a couple more markers for new files in current libunwind.

Before this patch you would get the following on selinux enabled
systems without allow_exec_stack: error while loading shared
libraries:

libunwind.so.7: cannot enable executable stack as shared object
	requires: Permission denied

After the patch that error disappears and all test results are similar
to the results on systems without executable stack protection.
