	.plt for prelinked libraries where prelinking info cannot be used.
	(elf_machine_rela): If relocating R_ALPHA_JMP_SLOT in .gnu.conflict
	section, use RESOLVE_CONFLICT_FIND_MAP to find out reloc's link_map.

	of adjusting it if prelinked and prelinking cannot be used.
	* sysdeps/powerpc/dl-machine.h (elf_machine_rela): If relocating
	conflicts, skip finaladdr computation.  Use RESOLVE_CONFLICT_FIND_MAP
