Apparently the NetBSD compiler-rt builds into the linux directory as well.
I'm... detecting a trend!
let arch = target.split('-').next().unwrap();
let mode = if build.config.rust_optimize {"Release"} else {"Debug"};
let (dir, build_target, libname) = if target.contains("linux") ||
- target.contains("freebsd") {
+ target.contains("freebsd") ||
+ target.contains("netbsd") {
let os = if target.contains("android") {"-android"} else {""};
let arch = if arch.starts_with("arm") && target.contains("eabihf") {
"armhf"
