[PATCH 0/1] Cross-compiling 32-bit macOS from 64-bit-only macOS.

[Brendan Shanks]

True, looks like even Xcode 13.1 RC is still able to build for i386 with the 10.13 SDK. For CrossOver though we build an i386 .app, which requires xcodebuild, etc.
I would also prefer to stick with the toolchain that Apple tested/supported for i386 (and that we’ve already been using).
