    build: Fix enum types rules
    
    The list of files being parsed for enumerations include the header file
    we are building with the enumeration types.
    
    Additionally, we are concatenating multiple runs in the same temporary
    files; on failure, the temporary files are left around, which means we
    end up with broken headers and sources.
