Analysis

On Ubuntu 24.04:

• libtinfo5 must be replaced by libtinfo6
• Many errors while extracting 7z archive with SDK due to unsafe symbolic links, eg:

  ERROR: Dangerous link path was ignored : SDK-B288/usr/arm-obreey-linux-gnueabi/sysroot/etc/fonts/conf.d/10-scale-bitmap-fonts.conf : /usr/share/fontconfig/conf.avail/10-scale-bitmap-fonts.conf
  

No urge to fix those things, the Ubuntu version will be fixed to 22.04 where the build works fine.
