Great news! Hopefully this means that Rust will now support GCC's supported architectures [0] in addition to their own quite impressive and continuously improving list [1] [2], including those that are less popular these days. I hope this will directly help issues experienced by the Debian Ports project [3] [4], Gentoo Linux [5] [6], and possibly Alpine Linux [7] and NetBSD [8].
