build: Use make in build.rs

Duh
Examples:
https://github.com/rust-fuzz/honggfuzz-rs/blob/912092c1f14a505d180d888894e895a5baed4839/build.rs#L9
https://github.com/avr-rust/libc/blob/1e3ce441d1a1839ac20213d8af42ae4ac4bdf528/build.rs#L57
https://github.com/glandium/git-cinnabar/blob/4c91b281ba237cab75484dcc1bf6c20ce6123e3e/build.rs

Thinking this could be a build step in nix or something too
