Summary: GCC expects to link in a crtsavres.o on powerpc platforms. On powerpc64 this is an empty file, but on powerpc and powerpcspe this does contain some save/restore functions, which may not actually be necessary for newer modern GCC and clang. This appeases the in-tree gcc, though, and is needed in order to switch to the BSD CRTRBEGIN. PR: 233751 Reviewed By: andrew Differential Revision: https://reviews.freebsd.org/D18826
