Additionally, I think it should be possible to compile with the
x86_64-linux-user target and then to run "make check-tcg" ... however,
that currently crashes with:
TODO qemu/tcg/tci.c:859: tcg_qemu_tb_exec()
qemu/tcg/tci.c:859: tcg fatal error
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
