I'm a little torn on this and whether we should make it use the same variables
as the other QA checks? Is there a reason the user would want to configure this
sanity check separately from the other sanity checks?

I'm not sure I can see a long list of different license checks we'd want to add
here?

The current sanity checks in insane.bbclass could do with some cleanup and
refactoring so perhaps this could be come a common function (and common variable
to control all the QA checks)?

Cheers,

Richard
