Is this the plan going forward? It does seem to tie the building of
these packages forever to amd64 which I grant given the current market
share will likely be the case for some time.

That worked thanks.

I've mentioned the reference to #846970 in replying to the #921458. I
take it there is no way of adding an explicit link between the bugs?
I'll close the bug presently.
Would it be worth opening a wishlist bug for better cross compiler
coverage on non-x86 architectures?
The QEMU project makes quite heavy use of the excellent multiarch cross
compilers that Debian provides but currently all the tooling for that
falls flat on it's face the moment you run it on a non-x86 machine. We
can work around it of course with linux-user powered images but it's
