Great, thanks. I got the compiler built with single threaded make, but it never hurts to have parallel make working properly.

It was an actual bug even for single threaded builds -- the test/demo program for libstd hadn't declared a dependency on the library.

I should really pull the test program out of there, and make it actually demo things nicely, rather than being an initial "let's see if the code I'm writing actually works" pseudo-test.
