powerpc64-linux infrastructure 2 of 6

[Alan Modra]

Another infrastructure change.  Allows OBJ_COPY_SYMBOL_ATTRIBUTES to be
defined to do some target specific twiddles, then call
elf_copy_symbol_attributes.

gas/ChangeLog
	* config/obj-elf.c (elf_copy_symbol_attributes): Make it a global
	function, and expand old obj-elf.h:OBJ_COPY_SYMBOL_ATTRIBUTES here.
	* config/obj-elf.h (elf_copy_symbol_attributes): Declare.
	(OBJ_COPY_SYMBOL_ATTRIBUTES): Call elf_copy_symbol_attributes.

Applying to mainline.
