Strangely, the answer as to what might be wrong occurred to me in the
shower this morning. We should try changing:

native.bbclass:    e.data.setVar("OVERRIDES", e.data.getVar("OVERRIDES", False) + ":virtclass-native")

to

e.data.setVar("FOO", "virtclass-native")
e.data.setVar("OVERRIDES", e.data.getVar("OVERRIDES", False) + ":${FOO}")

and if that makes things work, its the override caching mechanism that
is bust for direct changes to OVERRIDES which don't use variable
indirection (most do).

If that is the case, a fix shouldn't be hard.

Cheers,

Richard
