quackboot (same idea as klompboot), from audit6

this is based directly on the audit6 final revision.

same idea as klompboot. remove u-boot and arm support,
remove pico-serprog, remove support for making release
archives, and basically see how small the build
system can possible get.

quackboot *beats* the very first klompboot, at 790 lines,
because klompboot 1 was just over 800 lines. klompboot 2
was 701 lines. vendor file logic is about 200 sloc so
the next klompboot will be about 600 lines.

this is the very first quackboot.
