That's good, let me devise a fix for that, throw it onto an Ubuntu
porter box and if all good upload into Debian & Ubuntu. Thanks a lot
for the idea.

The typo in the patch that disabled building mpi components.
Another typo that doesn't disable pch during python/mpi builds.
And missing set -e on our part to catch above.

I'll go file a bug there when I get a bug number for this bug.

No need, I maintain boost in ubuntu, and was aware of the issue, but
didn't have time to dig into which gcc upload regressed on this. Since
there is no code changes in boost that would have caused boost arm64
FTBFS on ubuntu.

> P.P.S. other versions of boost also FTBFS on debian arm64 but I have not investigated why
