At <http://gcc.gnu.org/ml/gcc-patches/2010-10/msg01104.html> I
enumerated the cases in GCC where WORDS_BIG_ENDIAN and
BYTES_BIG_ENDIAN may differ. The ARM -mwords-little-endian case has
now had a deprecation patch submitted
<http://gcc.gnu.org/ml/gcc-patches/2011-06/msg02217.html> and approved
(with changes) but apparently not yet committed. This patch fixes the
powerpc-wrs-vxworks* case, where as I noted before it's clearly a bug
to undefine and redefine only one of the two macros.
Tested building cc1 and xgcc for cross to powerpc-wrs-vxworks.
Committed as obvious.
