DEV_FOO is defined instead of FOO in the opt_*.h file is the only
difference since otherwise both are added. I think that config's grammer
only lets option foo=bar work, while device foo=bar does not.

For options like filemon that conditionally include whole files without
ifdefs elsewhere, there's no difference.
