They do.

I think I can do better: apparently I have found the culprit. In the Features 
section of qtmultimedia/src/multimedia/configure.json:

        "pulseaudio": {
            "label": "PulseAudio",
            "autoDetect": "config.unix",
            "condition": "libs.pulseaudio",
            "output": [ "feature", "privateFeature" ]
        },

Removing the "autoDetect" line solves the issue. As far as I can tell this 
doesn't interfere with auto-detection on Linux (tested with `configure -redo -
recheck-all` WITHOUT any -pulseaudio option).

Works.
