/bin/sh would be the canonical dependency. I don't think the actual behavior
results in problems.

I did this because USE_LINUX was a trigger variable before. If set to any
value (even "no"), it triggered a dependency to the default linux base.

We have several of such trigger variables. I don't think we should change
that (for USE_LINUX only). If you think that we should get rid of trigger
variables, it should be done for all trigger variables at once.

Personally I think we should fix up the docs to explain that "no" doesn't
DTRT for those variables instead.

Bye,
Alexander.
