* elf32-spu.h (struct spu_elf_params): ovly_flavour now only 1 bit.
	Add compact_stub.
	(emum _ovly_flavour): Delete ovly_compact, ovly_none.
	* elf32-spu.c (struct spu_link_hash_table): Replace ovly_load and
	ovly_return fields with ovly_entry[2].  Adjust all users.
	(spu_elf_find_overlays): Set ovly_entry[1] from __icache_call_handler
	when soft-icache.
	(spu_elf_build_stubs): Likewise.
