Can we just remove this now?

[no longer working on chromium, 2013/02/15 16:07:33]

I prefer to do it on another trivial CL. After testing with webrtc, webaudio,
pepper, and audio tags.

                 '<!@(pkg-config --cflags libpulse)',

Delete?

[DaleCurtis, 2013/02/15 00:28:51]

Why all this? We don't exclude audio_manager_linux?

[no longer working on chromium, 2013/02/15 16:07:33]

audio_manager_linux is automatically excluded because of being in linux folder,
but we need to exclude pulse explicitly.
