Configure gcc to emit .note.GNU-stack for both 32 and 64 bits PowerPC.
Mark gcc-provided asm files as not requiring executable stack.

It seems that non-FreeBSD ABIs for powerpc64 claim stack non-executable.
Due to this, rs6000_elf_end_indicate_exec_stack() only emit the note for
32 bit target. I decided not to change FreeBSD ABI and patch
emit the notes for both variants.
