Fix powerpc-nofpu remainderl wrong sign of zero result (bug 22688).
For soft-float powerpc, the remainderl function produces zero results
with the wrong sign for various inputs. This is another instance of
the problem with incorrect built-in fabsl expansion, so is fixed by
this patch using -fno-builtin-fabsl for this function.
Tested for powerpc (soft-float).
[BZ #22688]
* sysdeps/powerpc/nofpu/Makefile [$(subdir) = math]
(CFLAGS-e_remainderl.c): New variable.
