What you were trying to do (and why)

Tried to run tests after build against openmpi instead of mpich on attempt to packaging new OpenCoarrays version 2.10.1.

What happened (include command output, screenshots, logs, etc.)

Some tests are failed with error ***Failed Required regular expression not found. Regex=[Test passed.]

Full build and test log

What you expected to happen

All tests are passed like if build and run tests for OpenCoarrays 2.10.1 built against mpich-3.4.3.
(Full build and successfully test log if build against mpich )

The OpenCoarrays of 2.9.3 and 2.10.0 successfully pass all test being built against openmpi-4.1.2 and 4.1.4.

Step-by-step reproduction instructions to reproduce the error/bug

• Install openmpi-4.1.2 or 4.1.4 instead of mpich -
  for previous versions of OpenCoarrays it was sufficient to install openmpi with next built-in options:
  sys-cluster/openmpi-4.1.4::gentoo USE="fortran -cma -cuda -cxx -ipv6 -java -libompitrace -peruse -romio"
  where - means that option is switched off.
• Build OpenCoarrays 2.10.1
• Run tests

The changes introduced in ed01646 results in this problem when openmpi is used.
