[Buildroot] [PATCH v2 1/1] webkitgtk: Allow building with BR2_PACKAGE_WEBKITGTK_MULTIMEDIA disabled

[Adrian Perez de Castro]

Explicitly pass "-DENABLE_MEDIA_STREAM=OFF" to CMake, to workaround a
missing feature dependency in the WebKitGTK+ build files. Additionally,
a patch for https://bugs.webkit.org/show_bug.cgi?id=174940 is needed.

Related upstream bug: https://bugs.webkit.org/show_bug.cgi?id=174940

I have already applied your v1, which did not include the patch. Can
you send a follow-up patch instead ?

Thanks!

Of course! I have posted the follow-up patch a bit earlier today:

  https://patchwork.ozlabs.org/patch/795273/

With this one applied, I was able of making a build for the Raspberry Pi 3
with BR2_PACKAGE_WEBKITGTK_MULTIMEDIA disabled.

(Sorry for the inconvenience, I should have checked that builds would succeed
before sending the v1 that you applied... WebKit builds take so long that
I assumed it would complete because the issue previusly reported was gone,
but I should have waited to make sure O:-|)

Regards,
