Mmm... what do you mean by supported architectures?
I'm not an expert Nios-II user (just started working on it) but there doesn't
seem to be any architectural variants.

Speaking of toolchains. Any recomendations on how to *choose* a toolchain?

Should I safely use Sourcery?
Should I prefer Buildroot internal (when we add support for it)?
Which should be the rationale behind such decision? (aside from the
fact the buildroot toolchain allows to be tuned)

Thanks a lot for the help!
