When you have this working could you add an integration test into the https://github.com/apple/swift-integration-tests repository to catch any future regressions? Thanks. There are some example tests in |

@spevans Okey, I'll add a test case in the repo. Thanks for letting me know :) |

`Foundation` imports `CoreFoundation` with `@_implementationOnly` as a private dependency, and it doesn't emit `IMPORTED_MODULE` in swiftmodule. Users of Foundation can link `libCoreFoundation.so` automatically when using dynamic linking because it's already linked into `libFoundation.so`. However, this automatic linking doesn't work when static linking, so users need to link CoreFoundation and dependent libraries of CoreFoundation explicitly by adding `-lCoreFoundation -lBlocksRuntime -licui18n`. To avoid forcing users to link private dependencies explicitly, this patch changed to merge the dependencies into libFoundation.a. And also to avoid forcing to link dependent libs of CoreFoundation like `curl` or `icui18n`, add `LINK_LIBRARY` entry in Foundation.swiftmodule using `-public-autolink-library` which is introduced by swiftlang/swift#35936
