  ldexpl: Simplify for platforms where 'long double' == 'double'.
  
  * lib/ldexpl.c (ldexpl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New
  alternative implementation.
  * m4/ldexpl.m4 (gl_FUNC_LDEXPL): Require gl_LONG_DOUBLE_VS_DOUBLE.
  Determine LDEXPL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
  * modules/ldexpl (Depends-on): Add ldexp. Update conditions.
