[Omake] Passing full target paths to compilers

[Benjamin Pierce]

Thanks, Jason -- That should do the trick for me.  I'm a little  
surprised, though, that this requires adding a flag to OMake itself:  
I'd have thought that it should be easy to do it entirely by  
programming within OMake, by adding a variable that changes the way  
rules are built by OCaml.om.  Is this not the case?
