It is possible, but I don’t know if swift-build supports it. We don’t really
have much comprehensive support for cross-compiling right now.
To cross-compile, you need to set the target, sysroot and tools-directory (the
latter only required if compiling an executable, not for swiftmodules). You
might also need to set the resource-dir to the lib/swift folder where the
target’s standard library is.
