Adding support for new boards without compiling TinyGo from scratch

[oxplot]

As I understand it, the only way to add support for new boards is to add certain board specific files and compile TinyGo. Is there plan to remove this requirement? Having to compile the entire thing is not in itself a big deal, but having to maintain a fork of the upstream is the time consuming part.

EDIT: In addition, any user of the board will have to use the fork and many would rather not.
