Adhemerval Zanella 58a813bf6e aarch64: Fix f{max,min}{f} build for GCC 4.9 and 5 
GCC 4.9 and 5 do not generate a correct f{max,min}nm instruction for
__builtin_{fmax,fmin}{f} without -ffinite-math-only.  It is clear a
compiler issue since the instruction can handle NaN and Inf correctly
and GCC6+ does not show this issue.

We can backport a fix to GCC 5, raise the minimum required GCC version
for aarch64 (since GCC 4.9 branch is now closed [1]) and/or add
configure check to check for this issue.  However I think
-ffinite-math-only should be safe for these specific implementations
and it is a simpler solution.

Checked on aarch64-linux-gnu with GCC 5.3.1.

	* sysdeps/aarch64/fpu/Makefile (CFLAGS-s_fmax.c, CFLAGS-s_fmaxf.c,
	CFLAGS-s_fmin.c, CFLAGS-s_fminf.c): New rule: add -ffinite-math-only.
