Thanks a lot. This *enormously* simplifies things. (After your initial
reply to the tlbuild I nearly lost hope, please don't repeat such
attempts ... :)

- We need "the latest" luatex. (It's not yet clear to me what "the
latest" means at this moment as it's still totally confusing to me and
we didn't configure the other builders yet either. Luigi sent me a
relatively confusing message about which branch should be used.)
- It would help to have a simple patch for
  to correctly detect the platform
- I would copy the TL binaries from you for now and later take them
from the subversion repository (I assume that would happen once the
updates are frozen).

That's something which I still believe should be somehow "hardcoded"
into LuaTeX itself, so that LuaTeX itself would be aware of which
platform it was compiled for. At the moment part of detection happens
in mtxrun, but that's somewhat strange.
