   4 Subject: [PATCH] configure: Switch to pkg-config macros.
   5
   6 All dependency libraries install pkg-config .pc files nowadays, which
   7 makes the process of looking them up a lot simpler. Get rid of the SDL
   8 workaround macro as it's not needed.
   9
  10 [Backported from upstream commit 3163bf87d7b955d08dedd5ebaccb1b2a86ffdcb9.
  11 Fixes static linking issues with SDL_mixer.]
