    powerpc: Fix llround spurious inexact on 32-bit POWER4 [BZ #22697]

    This issue is similar to BZ #19235, where spurious exceptions are
    created from adding 0.5 then converting to an integer.
    The solution is based on Joseph's fix for BZ #19235.

        [BZ #22697]
        * sysdeps/powerpc/powerpc32/power4/fpu/s_llround.S (__llround):
        Do not add 0.5 to integer or out-of-range arguments.
