Rust uses LLVM to generate the actual images.

But it should be a native-input since mrustc doesn't use it, only Rust uses it.
(But mrustc compiles parts of the Rust source code for use in minicargo)

Hmm, good to know.  Right now we use 5.5 since that's what the rest of Guix uses.
Let's see whether it's enough.

Right, it's a leftover from when I tried to get rust-1.19.0 to use gcc to link
its executables.  I might need to adapt it to "symlink gcc cc" in a later version
still.
