The commandline parsing for abuild doing a couple of buggy things:

* Long options of the form --opt=arg were not having the arg stripped
  off into a another argument in the output. As a result, all long
  options with args had to be written like "--opt arg" on the command
  line to be recognized.
* The --remove option was shifting too many times.

As a bonus, I also added some logic to make "make distclean" cleanup
the default abuild build dir.
