SPARC config files cleanup 1/n

[Eric Botcazou]

In the process of untangling the dependencies on the Solaris config files 
SPARC embedded targets have developped over the years, which will essentially 
boil down to folding sol2.h and sparc/sol2.h into sparc/elf.h and sp64-elf.h, 
I stumbled upon a difficulty: one of the native platforms (OpenBSD) is not a 
good citizen in that it includes sp64-elf.h, which should be reserved for
embedded 64-bit targets.  [Marc, when you have some time to kill... :-)]

As a few new macros will be added to sp64-elf.h, they probably will need to be 
explicitly undefined for OpenBSD.  So I'm doing a quick pass on the macros to 
clean things up.  And it starts with ASM_OUTPUT_INTERNAL_LABELREF, whose only 
use was removed by

	* sparc.h (ASM_OUTPUT_INTERNAL_LABELREF): Delete.
	(FUNCTION_PROFILER): Use ASM_GENERATE_INTERNAL_LABEL instead.

Tested by building a cross from Linux to every affected platfom, applied to 
mainline.
