+glibc headers define both __LITTLE_ENDIAN and __BIG_ENDIAN
+which was tripping the check in linux/byteorder.h.  Let's
+just stay out of userspace's way and use __KERN_{endian}
+
+The old implementation got away with it as it kept the two
+implementations in different headers and conditionally included
+the right one.  The combined header does checks within each
+function body and depends on only one being defined.
+
+Converted the arches in mainline that have already moved to the
+new header, as the other arches merge the will need simlar
+fixups.
