Aaah, seems like a very good idea. This would solve all the circular
dependencies we're seeing, with essentially no additional complexity.

The only downside is that the python3 util-linux support would not work
in static-linking scenarios, because in such cases dlopen() is not
available. But python3 anyway has "depends on !BR2_STATIC_LIBS", so
we're good :-)

Adam: could you look at implementing this solution, and do a runtime
check that the uuid-related feature of Python 3 are working as
expected ?

Best regards,

Thomas
