* force dwarf-2 - the kgdb shipping right now doesn't know about dwarf-4
  and LLVM in freebsd for a while did dwarf-4 for kernel builds.  Ugh.
  Setting the debug flag in the kernel config didn't seem to work for
  module builds.
* set the path to be my homedir - I had issues with relative paths.
add some more modules to the build list.
