Hmm, difficult. We have only defaulted to uClibc-NG since the 2015.08
release, so that's not that long ago (and people can build uClibc based
external toolchains outside Buildroot), but on the other hand you are
basically on your own if you use a custom uClibc based toolchain that
isn't in sync with how we build them - So I would say, go for option 2.

Yann, do you agree?
