Bug#905050: mpv: why does mpv tell it's built on unknown [PATCH]
Control: tags -1 + patch
[resending as debbugs seems to have ignored my first attempt]
One way of fixing this bug is to set the BUILDDATE variable
based on the timestamp of the most recent debian changelog entry.
That way BUILDDATE contains a sane date instead of "UNKNOWN",
but the build is reproducible (all builds from the same source
package version will have the same date).
Patch attached below. In order for it to take effect, it is
necessary to remove --disable-build-date option in debian/rules,
i.e. revert the patch from https://bugs.debian.org/784267
