Remove x86_64 __GNUC_PREREQ (4, 6) conditional.
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.
