[LinuxBIOS] [BUILDROM]: Disable OFW

[Jordan Crouse]

Okay, now that everybody has recovered from the last patch, here's the 
last one - disable OFW for the short term in buildrom.  Reason being,
that it only worked for OLPC, and the previous patch removed OLPC.   I
discussed the matter briefly with Stefan and Segher, and they tell me
that there are ongoing efforts to make OFW or a OpenFirmware clone of
some sort usable on a generic x86.  I support that 100%, I think OFW
is a vital payload for this project.  I just don't know enough about
OpenFirmware to get the job done.  So I am submitting a patch to
disable, but not to remove the OFW scripts, so that those who do know
what they are doing can port the code easily.  When everything works,
revert this patch, and we're off to the races.
