move these files into the ONIE repo ?? about build-onie

[bluejumper]

Hello cbrune,

I'm very open to including this Dockerfile within the ONIE repository. A tool like Docker and this file should improve the build process for a lot of users, and would greatly reduce the difficulty and time needed to deliver a successful software build. It should be in the hands of the developers involved with ONIE. And they are very welcome to suggest and improve upon these tools. By no means am I an expert, and so I am humbled to have the opportunity to review a contribution.

You raise a very good point about using make debian-prepare-build-host. It was where I obtained the dependency information and I was unaware that it was to be used as a make procedure. Aha!

I would raise a question of whether one would like the dependencies included within the container. There are two perfectly valid ways of approaching a primed build environment: a ready-to-order Makefile or a factory-made Dockerfile. A container can be expected to include dependencies. In fact, it is possible for the Dockerfile to rely on the same dependency list as Makefile.

I will offer a solution in a future commit, I'll add better polish 😄 In the meantime, you have the freedom to pop this in the ONIE repository. I could show my folks at home when it's done!

Many regards!
