Update: The bootstrap example script now handles building using fake.

Update: The bootstrap example script now handles building using fake.

The bootstrap example script is generally for using bootstrap scripts.

I have ended up using this for regular building because it is simple and already written.
The FLL 0.7 development now has build settings for some programs that do not build using the bootstrap without additional parameters.

Add support for the bootstrap script to use `fake` directly if it exists in the PATH for these particular programs.
