Parallel build on SMP is even more broken.

All this makefile mess is mostly my fault - I didn't test it with 
-jN because my system does not support that (no matter how funny 
does it sound. And, yes, I'll get A Real OS ASAP).

I apologize for that. However, I must say that this patch was posted 
back in May for a review, but nobody cared to write a single word
about it. Later I kept reminding about it every month, as web page
suggests, still without no success. But when it was checked in,
the problem was seen and solved in less than one day.

Said that, I'm sorry and I'll do my best to avoid such problems.
However, it would be _much_ easier if I get _any_ feedback...
