From 4b6ceb48080044d675bc67ac93a86513b61eea63 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix illegal syntax in configure script
Indirect expansion (`${!foo}`) is a bashism, it's not POSIX-sh
compatible and is not supported by common shells except Bash and ZSH!
Configure script should be portable, hence strictly POSIX compliant.
Moreover it has shebang /bin/sh.
