Hello!

This patch enhances libc's mathinline.h header to use some missing builtins
(mainly rounding builtins) that were added during 4.0 timeframe.

	* sysdeps/i386/fpu/bits/mathinline.h (__pow2): Define
	using __builtin_ldexpl and __builtin_exp2l for GCC 4.0+.
	(floor, floorf, floorl): Define using __builtin_floorl for GCC 4.0+.
	(ceil, ceilf, ceill): Define using __builtin_ceill for GCC 4.0+.
	(__ldexp_code): Define using __builtin_ldexpl for GCC 4.0+.
	(rint, rintf, rintl): Don't define for GCC 4.0+.
	(__lrint_code): Define using __builtin_lrintl for GCC 4.0+ with
	__FAST_MATH__.
	(__llrint_code): Define using __builtin_llrintl for GCC 4.0+ with
	__FAST_MATH__.
