sparc: refactor sparc32 nearbyint{f} selector to C
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/sparc32/sparcv9/fpu/multiarch/s_nearbyint-generic.S:
New file.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint.c: Likewise.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-generic.S:
Likewise.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.c:
Likewise.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint.S: Remove
file.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.S:
Likewise.
