This patches consolidates all the powerpc ceil{f} implementations on the generic sysdeps/powerpc/fpu/s_ceil{f}. The generic implementation uses either the compiler builts for ISA 2.03+ (which generates the frip instruction) or a generic implementation which uses FP only operations. It adds a generic implementation (round_to_integer.h) which is shared with other rounding to integer routines. The resulting code should be similar performance-wise to previous assembly one. The IFUNC organization for powerpc64 is also change to be enabled only for powerpc64 and not for powerpc64le. Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with
