@swift-ci Please Build Toolchain macOS Platform

[tomerd]

@elsh in order to build a toolchain, you need to create a PR on the swift repositories and then mention all the related PR (like this one and the llbuild one) for cross repo building. iow, the SwiftPM repo is not setup to create toolchains, you have to create an empty PR on the swift toolchain to do that.

probably worth adding at least one fixtures in the functional tests area for a end-to-end test of the functionality

Planning to add that in a separate PR; lmk if you think it should accompany this PR.
