example of build using dynamically generated config

[ipelupessy]

this is a proposal for getting more dynamic build configuration

the example lets a build use a dynamically generated config.mk (well at the moment just a verbatim copy of the static configuration; but the point is you could change the copy incrementally to use updated info)

admittedly its a bit of a hack (needs testing)

this is wip on #577 it needs latest amusifier patches

I like this, but I hesitate to merge it since it's just implemented for SSE - it's harder to debug if different packages behave differently...
