This is the patch that Scott is referring to.  I've never been very happy with 
it which is why I haven't submitted it before.  But now we're close to 2.1 
perhaps it should go in regardless unless someone can see a problem.

	* sysdeps/arm/bits/endian.h (__FLOAT_WORD_ORDER): Define to big
	endian.
	* math/math_private.h: Use __FLOAT_WORD_ORDER rather than
	BYTE_ORDER.
	* string/endian.h: If __FLOAT_WORD_ORDER wasn't defined by
	<bits/endian.h>, make it the same as __BYTE_ORDER.
