Linux installer's Forge causes MATLAB to crash

The Forge included in the official Linux installer is currently causing MATLAB to crash (segfault) when an ArrayFire mex-code is run (the below example causes this).

```
#include "arrayfire.h"
#include "mex.h"

void mexFunction(int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[])

{
const char * c = af::infoString();

mexPrintf("\n%s\n", c);

plhs[0] = mxCreateString(c);
}
```
On Windows, using the installer and MATLAB has no issues. Furthermore, building AF from source with Forge ON (or OFF) also works. If these built Forge libraries are replaced with the ones from the installer, the crashes start to occur. Removing the Forge libraries altogether removes the crashes.

This occurs both with AF 3.7.1 and 3.6.2 (where the no-gl installer works). GCC/G++ used was 7.5.0 with Ubuntu 18.04.
