From: Bruce Rogers Date: Sat, 19 Nov 2016 08:06:30 -0700 Subject: roms/Makefile: pass a packaging timestamp to subpackages with date info Certain rom subpackages build from qemu git-submodules call the date program to include date information in the packaged binaries. This causes repeated builds of the package to be different, wkere the only real difference is due to the fact that time build timestamp has changed. To promote reproducible builds and avoid customers being prompted to update packages needlessly, we'll use the timestamp of the VERSION file as the packaging timestamp for all packages that build in a timestamp for whatever reason.
