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

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 on ppc64le
and am about to revert once a bit more testing is complete.

It's definitely the DSE patch.  AIX bootstrapped but had many more
testsuite failures.  With the DSE patch removed, the testsuite
failures are corrected.
Yea. The bootstrap comparison failure is definitely DSE. I'm testing a fairly trivial patch right now.
