A few nits.
r- because  it implements it in the case where it should probably stay unimplemented...

>  #else

Is there a specific benefit in enabling it for everything else? Why not limit to LINUX + CHROMIUM? If the bug is about Chromium Linux implementation, then it should be narrowly scoped, otherwise there should be a note why specifically the previously unimplemented functionality should be implemented.

.. / sizeof(randomData[0]) ?

> WebCore/platform/UUID.cpp:113
> +    builder.append(String::format("%03x", randomData[2] >> 16));

seems it has to be (randomData[2]  >> 16 ) & 0x00000fff here...

Why don't we just use this code on all platforms?  I don't see the value in calling the platform-specific libraries.

I will watch this for a while. If we do not see any problem, we can start to extend to all other platforms.
