powerpc: Dump dynamic relocation info to the map file 

Dump dynamic relocation info to the map file when generating dynamic
relocation in read-only section relocations if -Map is used.

	* elf32-ppc.c (readonly_dynrelocs): Add a link_info argument.
	Dump dynamic relocation in read-only section with minfo if
	needed.
	(ppc_elf_adjust_dynamic_symbol): Pass NULL to readonly_dynrelocs.
	(maybe_set_textrel): Likewise.
	(ppc_elf_size_dynamic_sections): Dump dynamic relocation in
	read-only section with minfo.
