	* embedspu.sh: Emit SPU ELF image to .data.rel.ro.speelf if
	pic or pie and image needs relocs.
ld/
	* emultempl/spuelf.em (base_name): New function, split out from..
	(embedded_spu_file) ..here.  Pass -fPIC or -fpie to embedspu
	invocation if we deduce a shared lib or position independent
	executable build by looking at ctrbegin* linker input files.
