/* Rust's build process has a few quirks :
- It requires some patched in llvm that haven't landed upstream, so it
compiles its own llvm. This might change in the future, so at some
point we may be able to switch to nix's llvm.
- The Rust compiler is written is Rust, so it requires a bootstrap
compiler, which is downloaded during the build. To make the build
pure, we download it ourself before and put it where it is
expected. Once the language is stable (1.0) , we might want to
switch it to use nix's packaged rust compiler.
NOTE : some derivation depend on rust. When updating this, please make
sure those derivations still compile. (racer, for example).
