libunwind makery inserts -nostdlib during linking
which fails the build on musl when security flags are enabled
since it remove ssp from linking, so add them explicitly
to SECURITY_LDFLAGS

disable tests for musl targets, tests use obsolete
posix APIs e.g. getcontext

patchout x86_local_resume() on x86, gets a working
linunwind on x86, it seems that it wont work even
in glibc case but lets leave it as it is for glibc
and apply the patch only for musl

gcc driver is fixed to pass correct options to linker to do secure plt
linking when enabled. however this option --secure-plt is not supported
by gold linker which is now passed by default from gcc driver. Hence
the build fails when using gold. Therefore when we use gold then we do
not use secure plt

Make backtrace() API's use conditional on glibc
this helps make libunwind compile on musl

libunwind: Invalid dwarf opcodes can cause references beyond the end of
the array

Off-by-one error in the dwarf_to_unw_regnum function in include/dwarf_i.h
 in libunwind 1.1 allows local users to have unspecified impact via
invalid dwarf opcodes.

- This recipe is useful for more than just pulseaudio, so move it to
  recipes-support.
- Rename to the correct upstream name, which corresponds to the library name.
  Keep a PROVIDES of libatomics-ops for compatibility.

- Depend on libatomics-ops unconditionally for all archs, as it's used by more
  than just arm, and currently the configure script auto-detects and enables
  its use based on the existence of its header, resulting in non-deterministic
  builds.
- Drop the ldflags bits which link against libatomic_ops, because libunwind
  doesn't actually link against it, nor does it need to, as it currently uses
  all inline functions from the header file.
