	Its not so much its misinstalled as the discovery that we want to 
compile 64 bit is apparantly discovered later after the offset flag has been
set. You have to specifically request 64 bit, by default it compiles everything
32. We need to do the equivelent of this:


powerpc64-*-linux-gnu)
   V_CCOPT="$V_CCOPT -m64 -fPIC"
   ;;


either higher in the file or in to an additional flag so that at least the 
-m64 and perhaps both are set when it looks for the offset bit (or of course
just remember to preset them before running configure which also works :-)). 
I believe its just an efficiency issue, it is doing unnecessary work to get
a 64 bit offset that it already has native (although it may not know that 
yet).
