Tidies up Makefile

* Fixes default target. It looks like target `all`
  was previously define first to implicitly set `build`
  to be default target, but since introduction `include`
  above the `all` target - now `BINGO` is default target.
  This change explicitly sets `build` to be default.
* Sets several targets as phony as they are not targeting
  a file and moves `.PHONY` closer to target definition
  for better visibility.
* Removes unused `wait` target
