Sorry for the delay. Here's that test:

I have confirmed that the test in !6 passes with the SDL currently in
unstable (before !5), fails after !5 but without 6f58f102, and passes
again with that commit added.

It would be great if SDL-dependent packages would phase out the pattern of
using sdl2-config for SDL and a hard-coded -l for the smaller libraries
like SDL2_ttf, and start using pkg-config. However, that would require
some mass-bug-filing and patches. 6f58f102 means we can avoid the
incompatible change, avoiding that MBF being a blocker for solving #909740.
