When I invoke build-script like so:
./swift/utils/build-script --debug-swift -R --stdlib-deployment-targets=macosx-x86_64 --swift-darwin-supported-archs "x86_64" --extra-cmake-options="-DCMAKE_EXPORT_COMPILE_COMMANDS=1" --skip-ios --skip-watchos --skip-tvos --reconfigure
I get this error while building Swift:
+ /usr/local/bin/cmake --build /Users/danielzheng/swift-merge/build/Ninja-ReleaseAssert/swift-macosx-x86_64 -- -j36 all swift-test-stdlib-macosx-x86_64 swift-benchmark-macosx-x86_64
...

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Does anyone know how to fix this? Currently, I work around it by manually invoking ninja swift-frontend swift-stdlib at this point.
I'm on macOS 11.5.1 and Xcode 12.3 (12C33).
