sparc64-linux busted as a cross compiler

[Alan Modra <amodra at bigpond dot net dot au>]

I thought I'd look into some of the reported sparc64 binutils
problems, but have run into difficulties building an x86-linux to
sparc64-linux cross compiler.

/usr/local/sparc64-linux/bin/ld: /usr/lib/crti.o: Relocations in generic ELF (EM: 3)
/usr/lib/crti.o: could not read symbols: File in wrong format

Ick.  My cross-compiler wants to use x86 crti.i???  Not hard to see
why, looking at the hard-coded paths in sparc/linux64.h STARTFILE_SPEC
and ENDFILE_SPEC.  Here's a suggestion that works for me building
crosscompilers (I can't test native).

	* config/sparc/linux64.h (STARTFILE_SPEC): Remove hardcoded paths.
	(ENDFILE_SPEC): Likewise.
	(STARTFILE_SPEC32, STARTFILE_SPEC64): Delete.
	(ENDFILE_SPEC32, ENDFILE_SPEC64): Likewise.
	(STARTFILE_PREFIX_SPEC): Define.
