commit 7b428e744b1ae62c8f26b4e1db487230b796c984

    Fix ldbl-128ibm nextafterl, nexttowardl sign of zero result (bug 19678).

    The ldbl-128ibm implementation of nextafterl / nexttowardl returns -0
    in FE_DOWNWARD mode when taking the next value below the least
    positive subnormal, when it should return +0.  This patch fixes it to
    check explicitly for this case.

    Tested for powerpc.

        [BZ #19678]
        * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c (__nextafterl):
        Ensure +0.0 is returned when taking the next value below the least
        positive value.
