Building with the standard system headers isn't a perfect match to the stand environment. Instead, copy over the files we know are safe to use and constrain what else is used. We use -nostdinc to achieve this. This also fixes issues with building 32-bit libraries on amd64 sometimes pulling in the wrong cpufunc.h giving an error now that we stop on errors. It will also enable an easier transition to lua boot. Sponsored by: Netflix
