* fix the automatic build system by compressing payloads if possible

and leaving enough room for a real payload (not /dev/null)

  This is a wonderful example why "uses" sucks.

* add Config-abuild.lb for those boards that dont build with 
  the default settings and a real payload:
  arima/hdama, amd/quartet, amd/serengeti_cheetah, ibm/e326

* if lzma is installed and a real payload is used, try compressing
  it. 

* fix a small bug in "abuild --help"

This patch is acked by me because its due to infrastructural changes only.
Flames welcome.
