2ec55de302 Properly place the NULL STT_FILE symbol revistited 
I was having a little closer look at what is going on here and noticed
that HJ unconditionally emits a NULL STT_FILE symbol before emitting
forced local symbols.  That means we really don't need a second pass
over forced local symbols.  The only reason for two passes is when
some forced local symbol can be emitted before the NULL STT_FILE.  So
I set about removing the second pass, updating the testsuite all over
again.  It's also unnecessary to emit the NULL STT_FILE when no
previous file symbol has been emitted.

	PR ld/17975
	* elflink.c (struct elf_outext_info): Remove need_second_pass
	and second_pass.
	(elf_link_output_extsym): Delete code handling second forced
	local pass.  Move code emitting NULL STT_FILE symbol later, so
	that it can be omitted if forced local is stripped.  Don't
	emit the NULL STT_FILE if no file symbols have been output.

35f82954b5 Properly place the NULL STT_FILE symbol 
We output a NULL STT_FILE symbol for forced local symbols so that they
are not associated with the STT_FILE symbol for real local symbols. This
patch makes sure that the NULL STT_FILE symbol is placed before forced
local symbols.
