Add a configure script
This configure script is similar to rust's in that it doesn't require anything like autotools, it's just a meta-script to "generate" a makefile and perform run-of-the-mill validation/discovery before the Makefile is run. The main purpose of this rewrite is to support multi-target and targeted builds. This will allow us to produce 32-bit snapshots for platforms as well as easily providing `./configure --target $foo` for initialization. cc #274
