Good! :-)

Yes, but not too many, I hope. It would be absolutely impossible to maintain
if too many (say 2 or 3) feature-patchsets were to be added. Remember that
patches will be applied in sequence, and if a patch from a previous feature
is required before another feature, then you're screwed. Unless we have
dependencies on feature sets. Which wil be horrible.

You are aware that buildroot can use crosstool-NG as a toolchain backend,
aren't you? It's not finished, but it kind of works. I yet have some stuff
to push upstream...
