The bug report I linked in mpi-defaults' README.source contains an
example.

the false positives could be just handled manually (i.e. listed in the
transition bug), I don't think there are many that links to both.

Also, please note that mpich never built on riscv64, and is not up2date
on hppa and ppc64.  I think at least the riscv64 should be handlded
first, so to avoid being in the same situation again when a single weird
architecture uses a different MPI implementation.
I'm CCing debian-riscv@lists.debian.org for this, in case you need help.
