Subject: [PATCH] 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.
