FMA and non-FMA performance are similar on SPR.

			Before          After           Improvement
reciprocal-throughput	12.226		12.4064		-1%
latency			49.4701		48.4424		2%

Since there is no real advantage for FMA, it isn't necessary.

This request comes from https://issues.redhat.com/browse/RHEL-1063
We don't see any real advantage because in upstream glibc underlying
function call

__ieee754_log
__log1p

are already FMA enabled and invoked via ifunc.

FMA version could be beneficial if the underlying function is replaced
by direct call.

Please do that to see if it improves performance.
