Adhemerval Zanella Netto Oct. 26, 2017, 7:06 p.m. UTC 
This patch refactors the sparc64 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
(s_isnan-generic.S).

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

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