libXt 1.1.1 cross compilation breakage

I should note that I was previously passing makestrs_CFLAGS= when
building and that looks like it has been replaced by XT_CFLAGS and
so...

XT_CFLAGS seems to be the problem for me on ppc as it is pulling in
the target headers and tripping up over:

include/bits/endian.h:34:4: warning: #warning Cannot determine current
byte order, assuming big-endian.

I understand the problem better now.  If this is a no-fix from your
end I can just update the build to prebuild with
make -C util makestrs CC=gcc CFLAGS= XT_CFLAGS=


take care,
