From 2e469aaabf1c296dbb058a6189a74352e9fb7089 Mon Sep 17 00:00:00 2001

Subject: [PATCH] configure: added `--enable-rpath` option.

If set, binaries will have rpath set to $ORIGIN/../lib. That means
that even using defaults (--prefix=/usr), you can install
it via DESTDIR anywhere in your system and binaries will work.

This is in preparation for BSD support.

Closes: #87 [via git-merge-pr]
