Seems like you're missing the blocks runtime. We now build and package a copy of the blocks runtime with libdispatch, so we should be using that. You should add BlocksRuntime under the libdispatch source tree to the include paths.
I have libblocksruntime-dev installed since it's one of the dependencies listed for building swift itself. I guess adding a -I<path_to_swift_toolchain>/usr/lib/swift/Block/ should work too. At some point I'd like to propose we add these paths automatically in swiftpm when building c/c++/objc code, assuming the libdispatch owners are okay with it.
Sure, I just mean it's on the list of required packages, so I have it installed and that's how I'm building sourcekit-lsp. I just copied and pasted the apt-get command from the swift README. If it's no longer required anywhere we could update the README.
