Building numpy on 3.3 with MSVC 2010 does not work

Reported on the distutils-sig by Paul Moore.

```
A quick test later:
No BLAS/ATLAS/LAPACK causes a string of warnings, And ignoring the
rest of the error stack (which I'm frankly not interested in investing
the time to diagnose and fix) I get "RuntimeError: Broken toolchain:
cannot link a simple C program". Which is utter rubbish - I routinely
build extensions with this installation.
