It looks like anchoring the search at the beginning of the line will
work around the problem.  I don't think that should cause any problems
for the case where this might actually be needed.  Here is a patch:

	* aclocal.m4 (ld_run_path): Anchor search at beginning of line to
	avoid GNU sed bug on HP-UX systems.  Use just one sed command.
