Simplify build system architecture optimization
This change to the build system rips out any usage of PROC along with
architecture-specific optimizations in favor of using -march=native where it is
supported. This fixes broken builds on 64bit Intel systems and results in
better optimized code on systems running GCC 4.2+.
