RTCW and Pi5, adaptations required, Dirty Hack works.

[frankygit]

IF THIS IS NOT FILLED OUT, THE TICKET WILL BE CLOESED

Describe the bug
RTCW Sourceport under PI5 compiles with the RetroPie-Extra Module, but does not load. Dirty hack described below.

To Reproduce
Steps to reproduce the behavior:

1. Install Retropie
2. Install Retropie-Extra with all modules
3. under Retropie-setup install RTWC port
4. Install all required files into ~/roms/port/rtwc directory
5. Launch RTCW Port (SP or MP)
   Expected behavior
   GUI should start

Screenshots

Gui does not start, when manually calling the executable following errors occur:

Device (please complete the following information):

• What model: Pi5
• OS: Raspberry Pi OS, latest Retro-Pie and Retropie-Extra
• Version Bookworm, Arm64

Additional context
I realized that an ARM, not an ARCH64 binary is compiled. Changing the target to ARCH64 in the script compiled an arch64 binary, however the problem persisted.
When removing the compiler switches and when also forcing the script to copy also the render libraries (not only limiting this to the x86 platform), a working arch64 installation was created.
No issues were found after playing multiplayer and singleplayer, everything runs very smoothly.

The script creates a working RTWC installation for my setup but it is a dirty hack and needs further adaptations to create working modules under different architectures. I hope this may help you to make the necessary adaptions (I am not a programmer).

Thanks a lot for maintaining all the scripts - I have already used several ones in the last few days and this collection was a key driver for me to play around with Retropie.
