PowerPC floating point little-endian [5 of 15] 

http://sourceware.org/ml/libc-alpha/2013-08/msg00085.html

Rid ourselves of ieee854.

	* sysdeps/ieee754/ldbl-128ibm/ieee754.h (union ieee854_long_double):
	Delete.
	(IEEE854_LONG_DOUBLE_BIAS): Delete.
	* sysdeps/ieee754/ldbl-128ibm/math_ldbl.h: Don't include ieee854
	version of math_ldbl.h.
