the code in GCC 7 explicitly sets the CAN_SANITIZE_UB how
i've done it in our reach over makefiles.

i'm at first only interested in making things work as they
are expected to upstream (which in this case, is gcc, not
their upstream :-).

you or someone else are welcome to advance this state again,
but i'm unlikely to look at it.

thanks.
