I notice a lot of see-sawing on Config.lb files. 

Please consider having multiple Config files for a given target. So, for 
example, you could have 

arima/hdama/Config.etherboot.lb
arima/hdama/Config.kernel.lb

and so on. Each Config tool should build to a different target directory, 
to make multiple concurrent builds easy.

The the buildtarget tool can default to <target>/Config.lb, but a user can 
also specify (in future) <target>/<some-config>
