Looks like I can reproduce the issue with -s i686-linux. I tried to build using Ruby 2.7 (we use 2.6 by default, and tests pass)

You can test with: --with-input=ruby@2.6=ruby@2.7

I'm not a Ruby user, so I won't risk sending a patch. Probably, since it's used only by rubocop as a native input, we can safely use a differert ruby package for this?
