*.o needs depenency on spin.tab.h

[DavidZemon]

The makefile needs a dependency added on spin.tab.h so that it can be reliably run with parallel jobs. Specifically, line 78. Without the dependency, it is possible to begin compiling some of the source code prior to spin.tab.h being generated.

Thanks David. I've updated the Makefile and I think parallel builds should be reliable now (I tested with -j4). There's one quirk, which is that the job to build spin.tab.c and spin.tab.h runs twice; I'll try to fix that later, but it doesn't seem to cause any harm.

Thanks. I've turned TeamCity back up to -j6 now that the change has been pulled into PropGCC :)
