    CI: collect certain intermediate files as artifacts
    
    When one of the linking passes fails, additional intermediate files are
    still in place. Having them available for analysis of the underlying
    problem can be pretty helpful. Collect some into a new intermediates/
    directory. (Nothing new will be collected if linking succeeds.)
    
    As the script is run with -e passed to bash, defer exit if the main
    "make" (or substituent script thereof) failed. This way more artifacts
    are collected, potentially making it easier to analyze the failure.
