* 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.
