Running Swift SDK generator on Ubuntu 22.04 host still produces Mach-O binaries of the Swift compiler #114

It looks like this is related to the fact that it's downloading the OSX package for swift 5.9.2: I tried passing the So, I think some additional patching needs to happen to get this to work correctly on Ubuntu 22.04. |

@MaxDesiatov @euanh I have more changes for the swift-sdk-generator which will download a Linux host toolchain the host triple is set to something like |
With #113, the SDK generator seems to successfully run to completion on Ubuntu 22.04:
