They're part of LLVM's representation of debugging information (as you
may have guessed). So if compiling with Clang you can just not pass -g
and you won't get any (or override with -g0 if your build system
already adds -g and it's inconvenient to avoid that). Other front-ends
will have similar options I expect.

You can run "opt -strip-debug" will remove it in that situation.
