Use fabs(f/l) rather than __fabs

A few math functions still use __fabs(f/l) rather than fabs, which
means they won't be inlined. Rename them so they are inlined.
Also add -fno-builtin-fabsl to nofpu powerpc makefile to work around
BZ #29253.

	* sysdeps/ieee754/dbl-64/e_lgamma_r.c
	(__ieee754_lgamma_r): Use fabs rather than __fabs.
	* sysdeps/ieee754/dbl-64/e_log10.c (__ieee754_log10): Likewise.
