Pre-compute object file names before Makefile generation

Add a virtual cmGlobalGenerator::ComputeTargetObjects method invoked
during cmGeneratorTarget construction.  Implement it in the Makefile
generator to pre-compute all object file names for each target.  Use
the results during generation instead of re-computing it later.
