When building the Linux userspace binaries, the external system headers may have already defined values for the __LITTLE_ENDIAN and __BIG_ENDIAN constants. Fix by retaining the existing values if already defined, since the actual values of these constants do not matter. Signed-off-by: Michael Brown <mcb30@ipxe.org>
