[PATCH] PPC64 _dl_lookup_symbol_internal clobbers fpr2

dl-runtime.os, dl-lookup.os, and dl-misc.os seem to be the minimum set to clean
up the dynamic relocation path so dropped dl-reloc and rtld from the
-msoft-float list.

strlen, memcpy, and memset are clean (rewritten in asm) but mempcpy, memmove,
memchr, and strnlen are not. So I added rtld-mempcpy etc to the list. This is
not required to fix this fpr clobber, but these functions should not be using
fprs anyway.
