	(elf_machine_runtime_setup): Simplify and correct expressions.
	(RTLD_START): Fix bug changing _dl_starting_up.
	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Added. Deal with

	* sysdeps/powerpc/dl-machine.h (elf_machine_rela,

	necessary, for 603/604 support. Add better support for large PLTs.
	(elf_machine_rela): Remove relocations that wouldn't work if
	anyone ever used them. Use memcpy for copy reloc, it'll be safe.
	Never target branch relocations at a PLT entry.

	* sysdeps/powerpc/bsd-setjmp.S: Make jump to PLT entry if we are
	generating PIC.
	* sysdeps/powerpc/bsd-_setjmp.S: Likewise.
