[MIPS] Workaround for bug in gcc -EB / -EL options.
Certain gcc versions upto gcc 4.1.1 (probably 4.2-subversion as of 2006-10-10 don't properly change the the predefined symbols if -EB / -EL are used, so we kludge that here. A bug has been filed at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29413. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
