PR explanation
This PR changes some prerequisites for building procedure for Linux.
Without installing gcc-multilib, gcc cannot compile 32 bit code at all. gcc-multilib depends on gcc, so no need to require gcc explicitly
Removed libsdl2 and openal. We don't need 64 bit libraries to compile 32 bit binary.
By trial and error, i managed to find out which version of Go is needed. Also i tested running compilation command using Go provided by Debian repository and it worked fine -- no need to taint system with Snaps, if user doesn't have any.
