- Support for CMOS options

- Workaround cmos tables overlapping the traditional bios data segment
- Fixes to the p4dc6 examples to be syntactically correct
- Fixes to NLBConfig to fix the previos syntax error ``option foo bar'' is invalid
- Update docmil_fil_inbuf to only be compiled when the appropriate options are set
- Updates NLBConfig.py to export the variables MAINBOARD && TARGET_DIR
  as well as correct specify the generated files
