Can't install gems cbor, raindrops, kgio, and stackprof

Hi,

Recently noticed failures in installing the following gems on VMs running Ubuntu Bionic. Each with a different weird and wonderful error.

The last successful collection of these were from Jan 7th so I think it may be related to the recent core18 to core20 change - https://github.com/ruby/snap.ruby/pull/26

It's possible it's commits around then, I'm not sure.

Tái hiện bốn lỗi cài đặt gem trên Ubuntu Bionic bằng Ruby snap, bắt đầu với thay đổi từ core18 sang core20 được tham chiếu trong ruby/snap.ruby#26. So sánh đầu ra của các native extension của cbor, raindrops, kgio và stackprof, bao gồm buffer.c, linux_inet_diag.c, ancient_ruby.h, accept.c và extconf.rb. Hoàn thành khi xác định và khắc phục được nguyên nhân tương thích của snap để cả bốn phiên bản được liệt kê đều cài đặt thành công.
