Failures building MPI with gfortran on 5.4.0-1071-raspi #81-Ubuntu (20.04)

Tried to run this on a cluster of pis running Ubuntu 20.04 - it failed trying to build mpi.

Is there a reason not to use the OS provided version of mpich, if available?

Error here:

Also tried with installing gfortran-10 and got similar errors. Seems to work OK on newer versions of Ubuntu on the pi.

@brauhausdc - Honestly I had the same issue on Ubuntu on GitHub Actions, not sure why exactly.

Regarding why I'm compiling mpich, I recall there being some issue with the version that was available for the Pi at the time I initially wrote this playbook for the Turing Pi 2 cluster. That problem may or may not be present anymore, though...

I was attempting to run this on WSL, and I managed to solve the issue by installing gfortran-10 with apt, then changing line 56 in main.yml to - ./configure --with-device=ch3:sock FFLAGS=-fallow-argument-mismatch FC=gfortran-10. Hopefully this helps someone else out there!
