By the next commit, the iBCS2 build would be broken.  I kept the build
glue and iBCS2 option in the conf/ to not make large churn if the
build is going to be restored.  If somebody has option IBCS2 in the
kernel config, it has to be removed.

I have pending patches which both restore the iBCS2 emulator build and
fix issues with the signal frame layout for the SCO binaries.  These
patches are not committable right now for non-technical reasons.
Either the reasons will be cleared, which would allow the commit and
re-connection of the iBCS2 to the build, or the emulator will be
removed from the tree since the code cannot be maintained.
