Subject: 	* emultempl/elf32.em (output_rel_find): Add "isdyn" param. 
 Put 	.rel.dyn before other reloc sections.  Don't stop looking for reloc 
 sections on finding one that isn't allocated.  Match .rel even when 
 placing .rela and vice versa, when setting last_rel and 	last_rel_alloc
 for the first time.  If no reloc sections in script, 	prefer allocated
 section over non-alloc. 	(gld${EMULATION_NAME}_place_orphan): Handle
 orphan .rel.dyn.
