[GOLD] powerpc target select

[GOLD] powerpc target select

[Alan Modra]

The powerpc do_recognize does nothing but match EM_PPC/EM_PPC64,
which can be done in target-select.cc:select_target().

	* powerpc.cc (Target_selector_powerpc::Target_selector_powerpc):
	Set EM_PPC64 or EM_PPC here.
	(Target_selector_powerpc::do_recognize): Delete.
