nmu mumps_4.10.0.dfsg-3 . s390x . -m "Binary-only non-maintainer upload for
s390x; no source changes."
I am not 100% certain on this, but I believe that the mumps package
needs a binNMU on s390x. Below follows what I have found so far.
Please feel free to let me know if I am incorrect.
While investigating why coinor-ipopt FTBFS on s390x, I encountered a
strange error in the config.log:

According to packages.debian.org, the file libblacs-mpich2.so.1 is in
the package libblacs-mpi1. However, here is what I found when I listed
the files in that package:
(sid_s390x-dchroot)roberto@zelenka:~/coinor-ipopt-3.11.7$ dpkg -L libblacs-mpi1

libblacs-mpi1:
Installed: 1.1-31.1
Candidate: 1.1-31.1
Version table:
*** 1.1-31.1 0

It appears that the NMU of 1.1-31.1 caused a rebuild that changed the
name of the library files. I downloaded the binary packages from
snapshot.debian.org and here is what I found:
roberto@vieques:~/s390$ ls
libblacs-mpi1_1.1-31.1_s390x.deb libblacs-mpi1_1.1-31_s390x.deb
roberto@vieques:~/s390$ dpkg -x libblacs-mpi1_1.1-31_s390x.deb 1.1-31
roberto@vieques:~/s390$ dpkg -x libblacs-mpi1_1.1-31.1_s390x.deb 1.1-31.1
roberto@vieques:~/s390$ ls 1.1-31/usr/lib/
libblacs-mpich2.so.1 libblacsCinit-mpich2.so.1.1
libblacs-mpich2.so.1.1 libblacsF77init-mpich2.so.1
libblacsCinit-mpich2.so.1 libblacsF77init-mpich2.so.1.1
roberto@vieques:~/s390$ ls 1.1-31.1/usr/lib/
libblacs-mpich.so.1 libblacsCinit-mpich.so.1 libblacsF77init-mpich.so.1
libblacs-mpich.so.1.1 libblacsCinit-mpich.so.1.1 libblacsF77init-mpich.so.1.1
It appears, according to the status page for libmumps-4.10.0
( https://packages.debian.org/sid/libmumps-4.10.0 ) that mumps has been
binNMU'd on nearly every architecture. If I understand the situation
correctly, I think that a binNMU on s390x will get libmumps-4.10.0 to
link against the new libraries created by the 1.1-31.1 upload of
blacs-mpi. The 1.1-31.1 upload appears to have been made after the
mpich maintainer uploaded the new mpich upstream version (3.0.4) which
turned the mpich2 package and associated library packages into
transitional dummy packages and put everything into mpich2 and new
associated library packages. Those new packages resulted in the rename
of the *-mpich2.so.* packages in libblacs-mpi1 to *-mpich.so.*.
The binNMU, I believe, will allow coinor-ipopt to successfully build.
