  copysignl: Simplify for platforms where 'long double' == 'double'.
  
  * lib/copysignl.c (copysignl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New
  alternative.
  * m4/copysignl.m4 (gl_FUNC_COPYSIGNL): Require gl_LONG_DOUBLE_VS_DOUBLE.
  Determine COPYSIGNL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
  * modules/copysignl (Depends-on): Add copysign. Update conditions.
