Sadly, UA sniffing instead of feature testing is done extensively. In an ideal
world, browsers would stop sending UA strings completely and web developers
would be forced^W encouraged to level up their game and move on to testing
browser features. Neat side effect: less chances for users to be tracked.

Anyway, forget about the rant: the fact is that we cannot reasonably break the
web like this. IMHO the -DUSER_AGENT_GTK_DISTRIBUTOR_NAME setting either:

 1. Does not change the UA string, or
 2. Is removed.

WebKitGTK+-based applications should all provide the same UA string, because
the rendering engine provides the same web features to them (for a given
WebKitGTK+ version). It seems like a bad idea that a build setting changes the
UA string.
