* math/math_private.h (__copysign): Define as builtin for gcc 4.

        (__copysignf, __copysignl): Likewise.
        * sysdeps/alpha/fpu/bits/mathinline.h (copysign): Don't define
        for gcc 4.0.
        (copysignf, copysignl, fabsf, fabs): Likewise.
        (__copysign, __copysignf, __copysignl): Remove.
        (__fabs, __fabsf): Remove.
