the build should use gcc from source control

[andrewbachmann]

The build should not use an external gcc. Regardless of which gcc is installed on the machine, the build should utilize the gcc from svn.

Since gcc lives in another repository module, we cannot refer to it. We should add a configure option for specifying the compiler instead.

I would consider this fixed with the new build system.
