This is to fix a further problem with merging resource sections. It turns

out that the section is supposed to be page-aligned, but the newly merged
section was not being padded out to a page boundary.  This meant that when
the executable was stripped a badly sized .rsrc section was written out.

	PR ld/16807
	* peXXigen.c (rsrc_process_section): Page align the new contents
	befgore writing out.
