I maintain maybe the only 32-bit Swift 5.3 toolchain right now, [available on any Android ARMv7 device running 7.0 or later](https://forums.swift.org/t/swift-toolchain-for-android/41158), and @uraimo has been [putting out 32-bit ARM builds for much longer](https://github.com/uraimo/buildSwiftOnARM). As Saleem says, 32-bit arches are supported but since not many are actively building for or maintaining those platforms, regressions have cropped up. I upstreamed [the small patch I needed for Android ARMv7 last month](https://github.com/apple/swift/pull/34160) (two of the changes were not Android-specific and fixed all 32-bit platforms) and if you share the link error you got, I'm sure that could be fixed too.
