It adds a couple of extra builds, but the reduced maintenance burden (which should ultimately result in an increase in accuracy being the instructions are on the same page), far outweighs the minimal cumulative SBU increase. Thomas's patch likely doesn't require much if any manual intervention.

Failed at the second hurdle.

The first GCC pass gets as far, in the `make`, as building the included zlib
and, whilst configuring that, ends with

Adding multilib support to Makefile in ../../zlib

Has my applying the Multilib patch not done all it should - it applied cleanly
as I noted above.
