Jim Wilson Dec. 2, 2017, 12:24 a.m. UTC 
I noticed a stray DWARF_DEBUG reference.  The DWARF1 support was removed in
2004.  So I did a quick find|grep and I found two more.  This patch removes
them.

This was tested with quick x86_64-linux and mips-wrs-vxworks builds just to
verify that they still build, and by hand checking the docs to make sure they
are OK.

Committed.

	gcc/
	* common.opt (use_gnu_debug_info_extensions): Delete DWARF_DEBUG from
	comment.
	* config/vx-common.h (DWARF_DEBUGGING_INFO): Delete undef.
	* doc/tm.texi.in (PREFERRED_DEBUGGING_TYPE): Delete DWARF_DEBUG
	reference.
	* doc/tm.texi: Regenerate.
