Shared Code Support

[weswitt]

I would like to see support for shared code across an Arduino target and another arbitrary target (like some Linux code).

When using a straight makefile based build system I'd use VPATH to facilitate shared code. There is nothing like that available with this CLI tool. The CLI is a great step in the right direction but I need more flexibility. I have some C++ file & headers that I need to share between Arduino code & non-Arduino code.

I wonder if the concept of environments (#108) couldn't help?

I think that putting the shared code in a library should do the trick?
