Why download these external packages?  That part should be parallel (if
their build systems handle it; it's a problem we know how to solve in
any case), so it's measuring more-or-less the same thing as PETSc's
build.  I'd rather see stripped-down configure because that is the part
that is characteristically different from PETSc build, and also likely
to show the greatest discrepancy.
