Bug#1116131: mpich breaks mpi-defaults autopkgtest on i386: Package mpi-c was not found in the pkg-config search path.

Dear maintainer(s),

With a recent upload of mpich the autopkgtest of mpi-defaults fails in 
testing when that autopkgtest is run with the binary packages of mpich 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
mpich                  from testing    4.3.1-3
mpi-defaults           from testing    1.18
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of mpich to testing 
[1]. Due to the nature of this issue, I filed this bug report against 
both packages. Can you please investigate the situation and reassign the 
bug to the right package?
