Issue Description:

ci.swift.org log: https://ci.swift.org/job/swift-PR-source-compat-suite-test-macOS/274/artifact/swift-source-compat-suite/FAIL_fluent_4.2_BuildSwiftPackage.log

To reproduce:

1. Install latest GM/Beta Xcode
2. $ git clone [email protected]:apple/swift-source-compat-suite.git
3. $ cd swift-source-compat-suite
4. $ git checkout add-fluent
5. (Un-apply xfail patch locally) $ git show ae01b83cc435d | git apply -R

To build Swift from scratch before testing:
6a. $ ./reproduce.py master --project-path fluent

Or if you've already built Swift:
6b. $ ./reproduce.py master --project-path fluent --swiftc path/to/swiftc

Note that this project has not been added to the suite yet. The log shown above is from the pull request test output. To reproduce this, step #4 is required, as the project configuration does not exist on master.

Pull request to add fluent to the suite: swiftlang/swift-source-compat-suite#223

I've xfailed the project so that we can finish getting it added.
