This is probably the bit where its building pseudo-native. It
effectively does:
bitbake pseudo-native
bitbake <original target>
so the pseudo-native bit is not very parallel. Its the lesser of several
evils. I have ideas to improve this but they're invasive, complex and
I'm not finding the time to look at that :(
Cheers,
Richard
