[Error] SIGSEGV (Address boundary error) on Fedora 28 -- possible dynamic library loading issue

Hello, having some trouble running this on Fedora 28. Tried both latest binary release and compiling from source. Both times the binary terminates with:

```
> ./systemshock
11:14:06 INFO InitMac.c:100: Starting Shockolate
fish: “./systemshock” terminated by signal SIGSEGV (Address boundary error)
```

If relevant, here's some output from gdb (the binary release):

```

It would seem something is wrong with dlopen or dynamic library loading.

In both the case of running the binary build and building from source I ran the SDL script (`install_32bit_sdl.sh`/`build_deps.sh` respectively) as root.
