This is the first in a series of 3 branches that I'm sending up for review

The other two coming are https://github.com/kaladron/llvm-project/tree/sysconf-wrappers and https://github.com/kaladron/llvm-project/tree/sysconf-arg-open-max

This PR is the cleanup that should make those easier to review.

Thanks!
