./mach build -d seems to succeed here.

So does ./mach build -d --no-default-features --features="glutin_app", and as far as I can tell it didn't build in bluetooth.

What error are you seeing / do you want help correcting with this branch?

It still seemed to build blurz for me, and error out linking it with dbus.

Hrm, I was unable to get this working either. Hopefully after I get us onto cargo workspaces (#12391), this can be retried and will be easier? Sorry I sat on this for so long!

rust-lang/cargo#3024 (comment) suggests that more code changes are necessary here. Closing, since this appears to have a solution now.
