Allow overriding rust dependency

Authored by jbeich on Dec 22 2018, 10:20 PM.



In order to prepare for future lang/rust updates, facilitate upstreaming (including new platform support), test nightly->stable workarounds (devel/racer, textproc/ripgrep) and debugging it maybe desirable to build consumers using lang/rust-nightly. So, let's expose RUST_CHANNEL via DEFAULT_VERSIONS where empty/unset RUST_DEFAULT would imply stable.

I don't have any objections to the idea, but I'd rather the values for RUST_DEFAULT are the package names rust and rust-nightly (similar to SSL_DEFAULT, ignoring base...) as all of the depends would be much simpler. Having an empty RUST_DEFAULT value select lang/rust is weird and I'd like the depends line to be immediately obvious to anyone. It also needs to be documented in

DEFAULT_VERSIONS+=	rust=rust-nightly
