  floorl: Simplify for platforms where 'long double' == 'double'.
  
  * lib/floorl.c: Include <config.h>.
  (floorl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New function.
  * lib/floor.c [!USE_LONG_DOUBLE]: Don't include <config.h> a second
  time.
  * m4/floorl.m4 (gl_FUNC_FLOORL): Require gl_LONG_DOUBLE_VS_DOUBLE.
  Determine FLOORL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
  * modules/floorl (Depends-on): Add floor. Update conditions.
