We are currently using prefix=/usr and includedir=/usr/include/mpich2,
so libs get installed directly in /usr/lib, and header files are in
/usr/include/mpich2.
We could use includedir=/usr/lib/mpich2/include, but I'm still not sure
that this is the correct way to solve that problem, instead of fixing
the build systems to be more tolerant about the location of MPI header
files.
