A patch for making autoconf 2.71 relocatable. It uses absolute paths in each of the binary scripts. This uses Perl `FindBin::Bin` to use relative paths.

0001-autoconf-2.71-make-binaries-relocatable.patch

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] refactor: make binaries relocatable

Uses the binary locations and relative paths to the
package data directory to avoid having absolute paths
baked into the binary scripts.
