Some mismatch... As usually, googling with the error message(s) could 
help. One useful skill more is to solve problems for which one hasn't
any clue :) OK, for instance this  was found :
https://www.linuxquestions.org/questions/programming-9/errno-tls-definition-in-lib64-libc-so-6-section-tbss-mismatches-non-tls-reference-528681/
The 'libvga' seems to be for direct access to the VGA display, which 
somehow reminds me about the IBM PC early years when DOS hadn't much
support for handling the display. Neither Linux in its early years 
before X11, KDE, Gnome etc. graphic support libraries. So my question is 
how old was
the system for which the application was aimed for? Should it still work 
in uptodate Linuces like Ubuntu 22.04? As was told, I have no clue whether a
"hack" like used in the link could solve your problem...
