Comment:
I tried testing on aarch64-musl, and found that:
```
=> OpenCoarrays-2.9.2_1: building [cmake] for aarch64-musl...
   [host] gcc-fortran-9.3.0_9: found (https://alpha.de.repo.voidlinux.org/current/musl)
   [host] openmpi-4.1.0_1: found (https://alpha.de.repo.voidlinux.org/current/musl)
   [host] cmake-3.19.3_1: found (https://alpha.de.repo.voidlinux.org/current/musl)
   [target] libgfortran-devel-9.3.0_9: found (https://alpha.de.repo.voidlinux.org/current/aarch64)
   [target] openmpi-devel-4.1.0_1: not found
```
`openmpi` isn't on cross platform. I have an updated template [here](https://pastebin.com/pZQzpSQB). I don't know much about fortran, though.
