Some adaptions for Linux/Raspberry Pi OS

[Gemba]

Hi there. Thanks for the Linux adaptions and esp. for the libretro core.

The LR core works fine on the current RetroPie (based on Buster) with some adaptions, see full story there: https://retropie.org.uk/forum/post/284130

TL;DR:

1. Workaround: static linking for stdc++ filesystem with GCC before v9 (C++17 Standard is supported but stdc++fs is marked experimental in GCC8):
