build: remove Linux boards from make

This way people don't copy and paste to add a new board: make build
system is deprecated for Linux boards for a long time and is now
unsupported.

qflight remains as the only Linux board since it's not buildable
with waf. When it is, more files and pieces can be removed from mk/.
