Don't use chew comments for static functions

I found a few static functions in the BFD manual.  These can't be
called by any user of the library, so I don't think it's useful to put
them in the manual.  This patch removes the chew markup from their
comments.

	* opncls.c (bfd_get_debug_link_info_1, separate_debug_file_exists)
	(separate_alt_debug_file_exists, find_separate_debug_file)
	(get_build_id, get_build_id_name, check_build_id_file): Don't use
	chew comments.
