Just that a bug existed for a long time does not mean it is not a bug.

The problem is really not that people think it works that way, but
rather that it actually works in a very confusing way.
Using --enable-sdl2 while libsdl2-dev is not installed does not cause
a configure failure, as it should, but instead causes the build to
fail later. Thus it achieves the desired end result, but in a very
confusing way. I really think this should be fixed.
