Adhemerval Zanella Oct. 26, 2017, 7:06 p.m. UTC 
This patch refactors the sparc32 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
s_nearbyint{f}-generic.S).

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

	* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile
	(libm-sysdep_routines): Add s_nearbyintf-generic and
	s_nearbyint-generic.
	* sysdeps/sparc/sparcv9/fpu/multiarch/s_nearbyint-generic.S: New
	file.
	* sysdeps/sparc32/sparcv9/fpu/multiarch/s_nearbyint.c: Likewise.
	* sysdeps/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-generic.S:
	Likewise.
	* sysdeps/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.c: Likewise.
	* sysdeps/sparc32/sparcv9/fpu/multiarch/s_nearbyint.S: Remove file.
	* sysdeps/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.S: Likewise.

If no one opposes it, I will commit it shortly.  I had to adjust to use
Joseph recent changes to use libc_alias_{float,double}.
