Subject: [PATCH] Leverage on rake-compiler for extension compilation

Rely on rake-compiler instead of handmade tasks to improve
portability and standardization.

This will allow in the future rely on the cross-compilation
functionality of rake-compiler to generate native gems for
other platforms (e.g. Windows)
