From 65cc6f263f1a2599576bc6e45e50587f1df4f068 Mon Sep 17 00:00:00 2001
From: agc <agc>

Subject: Add an EXTRACT_USING_PAX definition, which, if defined, will use
 pax(1) to extract archives when building, rather than GNU tar. This is needed
 on platforms where GNU tar is not the standard version of tar, and by people
 who prefer to use pax(1) in general.
