This package creates symlinks in /usr/bin/rust* -> rustup for the programs
managed by rustup. But it leaves out rust-analyzer, which is available with
current Rust versions. See ~/.rustup/toolchains/*/bin/*, the only one missing
for the current toolchain is rust-analyzer.

```
trs@jelly:/usr/bin/ > ls ~/.rustup/toolchains/*/bin
cargo         cargo-fmt      rust-analyzer  rustdoc  rust-gdb     rust-lldb
cargo-clippy  clippy-driver  rustc          rustfmt  rust-gdbgui
