This patch refactors the sparc64 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
s_finite{f}-generic.S).

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

	* sysdeps/sparc/sparc64/fpu/multiarch/Makefile (sysdeps_calls):
	Add s_finitef-generic and s_finite-generic objects.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finite-generic.S: New file.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finite.c: Likewise.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finitef-generic.S: Likewise.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finitef.c: Likewise.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finite.S: Remove file.
	* sysdeps/sparc/sparc64/fpu/multiarch/s_finitef.S: Remove file.
