WIP: Trying out a Machinekit branch

Whom this is for

• you’re used to using LinuxCNC/Machinekit from packages, but never tried git, or building from source

• now some fellow announces a feature which sounds interesting, and asks on the list to 'go try it out, the branch is foo in git repository bar'

• instant 'deer in the headlights' time - how do I go about all this git mumbo-jumbo? will I loose my configuration?

This note intends to cover this common case - in two parts:

• prepare your platform for building from source if that never happened before - this is a one time effort

What we’ll cover:

The assumptions are:

• the platform you’re building on has all preqrequisite packages for the build installed. This is true for all Beaglebone SD images; and if you ever built successfully from a 'git clone' command.

• We’ll put make a minimal copy
