This reduces rustc's size from 359 MiB to 186 MiB. Maybe we should disable doc generation altogether, since it's very slow and people who need docs will JFGI anyway. But for now I've left it.

/* 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).
