Subject: [PATCH] configure.ac: allow to disable nfsrahead tool
Date:   Tue, 20 Sep 2022 00:18:32 +0200

This allows to make libmount not mandatory but depending on nfsrahead
since it only requires it. This is useful when cross-compiling because
in that case we need rpcgen only built for host but not nfsrahead that
also require libmount. So this reduces the dependencies for host
building.
