User:Aslantis/Lesser known optimization flags for make.conf

This is my list of certain optimization flags you can set in your `make.conf`. I decided to start this after learning about optimization flags that I didn't know you could set for rust, and got curious about other possibilities so decided to start a running list!!

If you know any other flags you can set for further optimizations, I'd appreciate if you added them to this page!! (or at least let me know about them in my talk page.)
