Research direction

No source files or tests are named. Reproduce the netcdf Fortran build in the impi container, then inspect the Autoconf checks shown in the configure output and how compiler support is detected. Done means unsupported flags are no longer added for mpiifort and the configure checks report the compiler capability correctly.

Written by the indexing model from the issue text.

Description

Autoconf is adding these flags to the netcdf fortran build even though they are not supported by the compiler.
