Between revision 244386 and 244448, aarch64-linux-gnu started to
miscompare bootstrap.

These are the options I used:
--prefix=`pwd`/../tools \
--enable-languages=c,c++,fortran,go \
                 --with-cpu=thunderx \
                 --disable-werror  --with-sysroot=/ --enable-plugins \
                 --enable-gnu-indirect-function \
                 --with-pkgversion="Cavium Inc. (Build ${BUILD_NUMBER})"

On another system I did bootstrap at revision 244392 just fine but
without the --with-cpu option.

I'm pretty sure its my DSE changes. I'm seeing similar failures onppc64le and am about to revert once a bit more testing is complete.
