[Vm-dev] attempting to build BochsX64Plugin on 32-bit Ubuntu

I removed the double-dots parent directory from the include statement 
with no change - still getting this issue and running out of ideas.

I changed: 
-I/home/rabbit/warren/oscogvm/build.linux32x86/squeak.cog.spur/build/../../bochs86
to: -I/home/rabbit/warren/oscogvm/build.linux32x86/bochs86
