    GetPrerequisites: Do not fail on files we cannot find
    
    Historically we have always warned and skipped missing files.  Since
    commit v3.4.0-rc1~264^2~1 (GetPrerequisites: Add error checks for
    execute_process() calls, 2015-07-29) we fail instead, but this was not
    an intentional part of that change.  Restore the warn-only behavior so
    that missing system libraries (e.g. during cross-compiling) do not cause
    failure.
    
    Closes: #16523
