[Omake] More 0.9.8.5 fixes

[Chris King]

Hi,

After upgrading to 0.9.8.5, I was having the same OCamlPackage problem
as Mike Furr, and applied the patches in that thread.  However, now I
have the opposite of his original problem: OMake now tries passing
ocamldep-omake the -package option:

- scan fr scan-ocaml-fr.ml
+ ocamlrun /usr/local/bin/ocamldep-omake -package extlib,threadsafe
-modules fr.ml
     | Shell.ocamldep-postproc()
/usr/local/bin/ocamldep-omake: unknown option `-package'.

setting OCAMLDEP=ocamldep in my OMakefile does not fix this problem.

BTW, it would be helpful if these patches could be packaged as a
release and pushed to GODI -- both Mike and I (as well as a few others
using OMake) are giving presentations next week at Jane St., and
they're all at 0.9.8.5.

Thanks,
Chris
