Building libunwind, then gcc-runtime causes build failures. This is hard
to fix since gcc-runtime wants the internal gcc unwind.h header but libunwind
wants to provide this. There are differences in include behaviour between gcc
and glibc which are by design.
This patch hacks around the issue by looking for a define used during gcc-runtime's
build and skipping to the internal header in that case. The patch is only enabled
on musl and is the best workaround I could come up with to unblock failing builds
on our autobuilder.

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

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.
