From 65f0c7278ec0c1cb197e3110e2bc4ebb4bd5caf4 Mon Sep 17 00:00:00 2001
From: Martin Roth <martin@coreboot.org>
Date: Sun, 9 May 2021 10:26:10 -0600
Subject: [PATCH 07/19] Makefile: Don't run genbuild_h if not doing a build
genbuild_h was being run on every make invocation - clean, distclean,
etc. to get the source date epoch value. This value isn't used unless
a build is being done, so don't run it on non-compile make invocations.
