modified make, fixed packages and vars

- the make helper now has distinct build stages
  - configure: is now defined in pkg.targets.configure
  - build: is now defined in pkg.targets.build
  - install: is now defined in pkg.targets.install
  - added pre-install: which is a list of targets that are looped over
before install
  - added post-instal: which is a list of targets that are looped over
after install

- removed major package level variables from vars/main.yml
  - moving those variables into actual package level variables as
defaults
  - if the values are defined they will be used instead of defaults
