I haven't tried any, do you know any widely available ones that I could
check?

If they aren't using the do_compile from module.bbclass, are they
inheriting module.bbclass anyway? If they aren't inheriting
module.bbclass, then they shouldn't be affected.

If they inherit module.bbclass, than I guess that we should remove the
call to do_make_scripts from their do_compile. _But_ this is untested,
as I've got no such recipe (that I'm aware of). If my assumptions hold,
we should probably rephrase the comment regarding do_make_scripts.

Cheers,
Anders
