Native make

Changes buildme script to work for native compilation on the Raspberry Pi.

This pull request is branched off the 'periodic timelapse' #74 pull request that has been hanging for the past month.  

My git-fu is weak so I don't know how to keep the pull requests isolated.  Rather than go through 3 cycles of 'try this rebase command' 'that didn't work, is this the equivalent?' 'no you have to squash...'', feel free to just make the changes.

Then I'll burn my fork down to the ground and start all over with my next set of changes.
