powerpc64le: Avoid conflicting types for f64xfmaf128 when IFUNC is not used

Avoid defining f64xfmaf128 twice when building s_fmaf128.c.
This can be reproduced on powerpc64le whenever f128 functions do not
have IFUNC enabled, e.g. using "--with-cpu=power8 --disable-multi-arch", or
when using "-with-cpu=power9".

Fixes: b3f27d8150d4f ("Add narrowing fma functions")
