But where to write the converted files, in the python
libs directory is not a good idea and if you would
write them in the build-temp directory you had to
add code to find_library_file().

It might be better to have script(s) in the misc directory,
which checks for a certain compiler the libraries and 
converts them if necessary.

The compiler classes would print a warning/error message
about the wrong format and could mention how to convert 
the library.
