Delete the makefile build system This PR deletes the makefile build system in favor of the rustbuild build system. The beta has now been branched so 1.16 will continue to be buildable from the makefiles, but going forward 1.17 will only be buildable with rustbuild. Rustbuild has been the default build system [since 1.15.0](https://github.com/rust-lang/rust/pull/37817) and the makefiles were [proposed for deletion](https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368) at this time back in November of last year. And now with the deletion of these makefiles we can start getting those sweet sweet improvements of using crates.io crates in the compiler!
