* mklibgcc.in: Correct calculation of libgcc_s_soname and
	libunwind_soname.  Use $out, not $outS, in commands for
	no-shared-library case.  Move EXTRA_MULTILIB_PARTS rules above
	library build rules, make $libunwind_so and $libgcc_s_so
	depend on them in the normal fashion, and filter those objects
	out of @shlib_objs@.
