Implementing feature request: <http://bugs.archlinux.org/task/4706>

* Added these three possible options (or !options, more likely), to the
  PKGBUILD possibilities:
  - ccache
  - distcc
  - makeflags
* Removed the --noccache and -j flags from makepkg as their functionality is
  better used by adding the above options to a PKGBUILD- keep the functionality
  where it is needed.

Testing would be appreciated, I didn't do much of that yet.
