A patch for libm

["H . J . Lu" <hjl at valinux dot com>]

Both libc and libm define the same functions. I don't think they are
necessary in libm. I did some tests. It seems safe to remove them
from libm. Here is a patch.

	* math/Makefile (libm-calls): Remove s_copysign, s_finite,
	s_frexp, s_modf, s_scalbn and s_signbit.

	* math/Versions (libm): Remove copysign*, finite*, frexp*,
	ldexp*, modf*, scalbn*, __signbit* and __finite*.
	(libc): Add __copysign, __copysignf and __copysignl to
	GLIBC_2.2.1 for libm.
