以前 HAProxy 1.8 をビルドしたことがあるのですが、最新の LTS 版の 2.2 をビルドしようとしたところ、ビルドオプションが一部変わっているようでした。
ディストリビューション標準の HAProxy のビルドオプションを確認してみました。

CentOS Linux release 8.2.2004 (Core)
CentOS 7：HAProxy 1.5
このバージョンでは Lua がサポートされていません。
Lua とはスクリプト言語で、バックエンドを制御できるようです。
自分の場合 Lua は使用していないので、最新の HAProxy でビルドする際も入れなくてよいですが、使用している方は注意しておいた方が良さそうです。
