[bug#46987] [PATCH] gnu: rust-1.19: Don't include i686-linux in supported-systems.

[Christopher Baines <mail@cbaines.net>]

Currently rust fails to build for i686-linux, so this will avoid computing
lots of derivations that depend on rust, but won't be possible to build.

* gnu/packages/rust.scm (rust-1.19)[supported-systems]: Switch hardcoding only
supporting x86_64-linux for supporting all supported systems, other than
i686-linux.
