A comment on that page says to use these flags (Chrome branding is not needed, only 
chromeos=1):

export GYP_DEFINES="chromeos=1 proprietary_codecs=1 ffmpeg_branding=Chrome"

do_configure succeeds but do_compile fails with "brlapi.h" missing. A google search
gave me this: https://groups.google.com/a/chromium.org/forum/#!topic/chromium-dev/StpTzFnf8ok
Supposedly, running "build/install-build-deps.sh" fixes it but it turned out it only fixes
things for building Chromium for the host and the script wants an Ubuntu host OS.

Is there a ready to use recipe for brlapi/brltty somewhere or should I make one?

Thanks in advance,
Zoltán Böszörményi
