[Qemu-devel] [RFC PATCH 1/4] docker: add debian-buildroot-base

[Alex Bennée]

We can build some more cross-compilers using buildroot. This base
system contains simply the minimum number of tools required for
buildroot to work. We also download and unpack the buildroot source
tree as that will be common for all system deriving from it.
