Subject: [BZ #2749]

* sysdeps/ieee754/ldbl-128ibm/s_copysignl.c: Include
<math_ldbl_opt.h>.  Remove weak_alias.  Use long_double_symbol macro.
(__copysignl): Use signbit() for comparison.
* sysdeps/ieee754/ldbl-128ibm/s_fabsl.c (__fabsl): Correct parms for
SET_LDOUBLE_WORDS64.
	[BZ #2423, #2749]
	* sysdeps/ieee754/ldbl-128ibm/s_ceill.c: Don't include <fenv_libc.h>.
	(__ceill): Remove calls to fegetround(), fesetround().
	* sysdeps/ieee754/ldbl-128ibm/s_floorl.c: Likewise.
	* sysdeps/ieee754/ldbl-128ibm/s_roundl.c: Likewise.
	* sysdeps/ieee754/ldbl-128ibm/s_truncl.c: Likewise.
