valgrind fails to build against openmpi-4

error: 'MPI_UB' undeclared (first use in this function)

Solution: rebuild openmpi with "--enable-mpi1-compatibility"
added to the slackbuild. support for this will go away in a future
release of openmpi though.

Upstream are aware. See https://bugs.kde.org/show_bug.cgi?id=401416
