The only case where built-in fabs (or copysign) may not work properly is
IBM long double in the soft-float case (see
sysdeps/powerpc/nofpu/Makefile). I'd expect the default to be that it
works with an override for long double fabs in that one soft-float case.

If this is fixing a bug that was user-visible in a release, there should
be a corresponding report in Bugzilla.
