Joseph Myers 22562bb222 Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390). ...

This patch fixes bug 16390, incorrect signs of zero results from
ldbl-128ibm atan2l, soft-float only.  The problem is a longstanding
GCC bug with fabsl not being correct for signed zero for soft float,
and the fix is using -fno-builtin-fabsl as a workaround, as already
done for various other source files.  Tested powerpc-nofpu.

	* sysdeps/powerpc/nofpu/Makefile [$(subdir) = math]
	(CFLAGS-e_atan2l.c): Use -fno-builtin-fabsl.
