commit b2584ac2a4d3d5ba7da01a52e6bbc495d61974c8

    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.
