Merge branch 'mahf708/ig/standalone-ghci-oci' (PR #6637)

Adds support for running eamxx standalone testing in the gh/ci containers, for now only single-precision tests due to a 
mix of issues. Addresses two issues that have already been fixed in the scream fork. Adds flexibility to build cprnc in 
eamxx.
