ld/ELF: refine fake STT_FILE symbol emission

Browse Source 
There's no real need to emit these always: They're needed only if we
indeed want to emit a localized symbol. Hence defer emission until we
at least did the basic early checks that would lead to no such symbol
getting emitted. This in particular avoids emitting such a symbol in
the majority of (if not all) "ld -r" cases.

I hope my set of cross build tests caught all the test cases needing
adjustment - please forgive if I missed a few.

	* elflink.c (struct elf_outext_info): Add field file_sym_done.
	(bfd_elf_final_link): Initialize new field. Move fake STT_FILE
	symbol emission from here ...
	(elf_link_output_extsym): ... to here.

	* gas/microblaze/relax_size.elf: Drop expectation of no longer
	present STT_FILE symbol.
