[PATCH] Fix prelinking on ppc32

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

When calling elf_machine_rela from dl-conflict.c, sym is NULL, so we
certainly cannot do checks on what it points to.

BTW: Shouldn't most of the TLS handling go into dl-machine.c on PPC32?
I mean, unless there are -fno-pic shared libraries, linker certainly
shouldn't keep any TLS relocs but R_PPC_DTPMOD32, R_PPC_DTPREL32 and
R_PPC_TPREL32 around and thus the rest doesn't hurt if it is slower.

	* sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela): Avoid
	checking R_PPC_RELATIVE, R_PPC_NONE and whether relocation is
	against local symbol in conflict processing.
