Summary: SDL 2.0 fails to load at runtime

Description Mathieu Comandon 2019-03-12 20:07:38 UTC 
After building the project on Ubuntu 18.10, I was unable to run any game using it, there seems to be an issue with loading the SDL2 shared libraries with dlopen.

Games will consistently crash with the following:

 ERROR: sdl12-compat failed to load SDL 2.0! Aborting!
 [1]    9699 abort (core dumped)  ./ut2004-bin

I had to pass custom arguments for the lib to build with the following command: 

 C_INCLUDE_PATH="/usr/include/SDL2" make

This was reproduced on UT2003 and Rune (32bit) and UT2004.

Reading through the code, the problem seems to be with the LoadSDL20Library function, the required file (libSDL2-2.0.so.0) is available for both 32 and 64 bit on the system.
