There is not enough space for both timestamp and package version, so
replace the timestamp by setting KBUILD_BUILD_TIMESTAMP.
We now need to get the distribution name in debian/rules.real, but
we already have DISTRIBUTION as the suite name so use DISTRIBUTOR for
the distribution name (!).
The utsname version string also appears in /proc/version and the init
banner, so don't bother including it again explicitly. This means we
no longer need to patch init/version.c and scripts/mkcompile_h at all.
Instead, split maintainer at the '@' and set KBUILD_BUILD_USER and
KBUILD_BUILD_HOST accordingly.
Carry on generating <generated/package.h>, but drop the parentheses
from LINUX_PACKAGE_ID now that it's not used in init/version.c.
Drop support for version.$DISTRIBUTION files. Any derived
distribution can set KBUILD_BUILD_* in the same way we are doing.
