This cuts down on the amount of data we need to ship and users need to keep on disk for each Rust toolchain. As noted in the added comment, there's not much going on in these executables, so the added benefit of symbols and debuginfo isn't large, while the cost is not insignificant. This takes each of the binaries (we store 4 identical copies under different names) from 3.7MB to 384KB.
