Yeah, but Rust tier 1 is only x86, x86_64, and arm64. And only Linux. That excludes MIPS, PPC, and arm32, all of which FreeBSD continues to support to varying degrees. x86_64-FreeBSD is a Rust tier 2 "it might work" target, as are arm6/7 and PPC. MIPS is Rust tier 3 "we don't build for it or test on it."
