the include was added to dispatch specifically to allow dispatch_io to build on intel so your patch I think would break Intel.
I think the general problem is likely that glibc is not module friendly today.

The PR hasn't gotten any where for various reasons. Currently, I've gotten libdispatch working on arm, but it requires a fix that's essentially identical. It is part of a PR available here: https://github.com/apple/swift-corelibs-libdispatch/pull/155 <https://github.com/apple/swift-corelibs-libdispatch/pull/155>
