Subject: 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.
	* sysdeps/ieee754/dbl-64/e_log2.c (__ieee754_log2): Likewise.
	* sysdeps/ieee754/flt-32/e_lgammaf_r.c
	(__ieee754_lgammaf_r): Use fabsf rather than __fabsf.
	* sysdeps/ieee754/flt-32/e_log10f.c (__ieee754_log10f): Likewise.
	* sysdeps/ieee754/flt-32/e_log2f.c (__ieee754_log2f): Likewise.
	* sysdeps/ieee754/ldbl-128/e_lgammal_r.c
	(__ieee754_lgammal_r): Use fabsl rather than __fabsl.
	* sysdeps/ieee754/ldbl-128/e_log10l.c (__ieee754_log10l): Likewise.
	* sysdeps/ieee754/ldbl-128/e_log2l.c (__ieee754_log2l): Likewise.
	* sysdeps/ieee754/ldbl-128ibm/e_lgammal_r.c
	(__ieee754_lgammal_r): Use fabsl rather than __fabsl.
	* sysdeps/ieee754/ldbl-128ibm/e_log10l.c (__ieee754_log10l): Likewise.
	* sysdeps/ieee754/ldbl-128ibm/e_log2l.c (__ieee754_log2l): Likewise.
	* sysdeps/powerpc/nofpu/Makefile: Add -fno-builtin-fabsl for BZ #29253.
