Remove x86_64 __GNUC_PREREQ (4, 6) conditional.

Browse Source 
This patch removes a conditional on __GNUC_PREREQ (4, 6) in x86_64
code.

Tested for x86_64 that installed shared libraries are unchanged by
this patch.  Committed (I think this file reasonably comes under math
maintainership).

	* sysdeps/x86_64/fpu/dla.h [__FMA4__ && __GNUC_PREREQ (4, 6)]
	(DLA_FMS): Make definition conditional only on [__FMA4__].
	[__FMA4__ && !__GNUC_PREREQ (4, 6)] (DLA_FMS): Remove conditional
	definition.
