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