hypre failing dwz on mispen

hypre 2.16.0-2 fails build at dh_dwz on mips, mipsel and mips64el, 
https://buildd.debian.org/status/package.php?p=hypre.  2.16.0-1exp1 
previously built successfully.

Building on eller,debian.org, dh_dwz -v gives more detail:

$ dh_dwz -v -O--sourcedirectory=src

I'm not familiar with dwz or these errors, so it's not clear to me how 
to proceed.  Is the problem related to the build failure of dwz 
0.12.20190711-1 on mipsen?  The version of dwz on the eller chroot is 
0.12.20190710-1.
