+Subject: [PATCH] configure.ac: allow disabling registry downloads
+
+Some environments require reproducible builds. Since the IANA PEN
+registry is constantly updating and there is no snapshot available,
+installing ipmitool via `make install` is not reproducible.
+
+Provide a configure mechanism to disable the registry download/install..
