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