I just have to clear a case where a new external package enables a
feature for a built-in package. So, br2-external could provide extra
./configure options for a built-in package.
But that has deep implications, especially if Buildroot is then
distributed as part of a compliance effort: only providing Buildroot and
not br2-external would not be compliant.
So, in fact, I don't think we should make that easy.

OK, I've fixed that now.

cryptodev is like jpeg: it provides a choice.

I've now converted both of them, too.

I think we should just convert them over to how other virtual packages
are implemented: there is nothing to prevent, eg. rpi-userland and
ti-gfx (both providers of EGL) to be selected at the same time.
OK, those are a bit special, since they are tied to the hardware, when
neither jpeg nor cryptodev are. But still, I think we should have a
single way of doing virtual packages.
Peter, what's your opinion?
