musl update, gcc fix for ssp on musl

This series bring musl to tip of tree.
backports gcc fixes to fix libssp detection on musl as well as unwinding
64bit musl targets e.g. mips64 did not define sitefiles correctly, as a result applications were failing to compile e.g. python-pygobject was getting incorrect sizeof ssize_t

1.8.3.1

Found that ssize_t was being wrongly computed for mips64 musl because it was using wrong cache files.

alias them to glibc versions, musl doesn't _yet_ have target incompatibilities to note in siteinfo thankfully.

Add musl aliases for aarch64 and ppc64 targets

1.8.3.1

We were trying to inject cached configure variables via EXTRA_OECONF, but that was not working due to the fact that gcc configure is called recursively via makefiles and hence these were getting lost.

These backports from master fixes the problem by
defining the options in configure itself

dl_iterate_phdr is provided by musl as well, so lets not depend on glibc defines like inhibit_libc alone
