Certain source files will not produce a .debug_info section. This patch to
google/main adds a check for that case to output_pubnames, preventing a link
failure.

Tested:
	By rebuild and bootstrap.

ChangeLog:

2012-01-09   Sterling Augustine  <saugustine@google.com>

	* gcc/dwarf2out.c (output_pubnames): Add check for info_section_emitted.
