<p>LLVM sets certain default configure options to make sure our developers don't
break things for constrained platforms. These settings are not optimal for most
desktop systems, and we hope that packagers (i.e., Redhat, Debian, MacPorts,
etc.) will tweak them. This document lists settings we suggest you tweak.
