	[BZ #6845]
	* sysdeps/powerpc/fpu/bits/mathinline.h (__signbitl): Copy new
	__signbitl definition and __LONG_DOUBLE_128__ guard from:
	* sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h: Remove as
	redundant.  Functions which call floating point assembler operations
	should go into a sysdeps powerpc/fpu directory.
