Provide stat function for spu overlay manager iovec

Browse source 
Commit f54498b4 broke spu-elf, specifically the change "Do not try to
load a string table bigger than the file", because bfd_get_size
returns zero for the spu built-in overlay manager bfd.

	* elf32-spu.c (ovl_mgr_stat): New function.
	(spu_elf_open_builtin_lib): Pass to bfd_openr_iovec.
