One fix would be to get both code and data into the same directory, do a

For checking, I create symlinks to /dev/null for files missing from
VERSION_DEPS, and make -k check now seems to be working mostly normally with
both tar sources, except tzdata is trying to rebuild executables, rather than
using the installed release.
Copying from /usr/*bin/ does not work. Any suggestions for an adequate bypass?
The simplest suggestion I can think of is the one quoted above. That is, when
building the data, don't merely download <https://data.iana.org/time-zones/
releases/tzdata2025c.tar.gz>. Instead, download the combined tarball <https://
data.iana.org/time-zones/releases/tzdb-2025c.tar.lz> (or, if you prefer,
download both <https://data.iana.org/time-zones/releases/tzcode2025c.tar.gz> and
<https://data.iana.org/time-zones/releases/tzdata2025c.tar.gz>), and build from
the combined set of files.
Similarly for tzcode. But come to think of it, there's little point to running
"make check" for tzcode, as the test cases all come from tzdata. So don't bother
trying to run "make check" for tzcode, and for tzdata follow the procedure
described above.
It should be possible to complicate the Makefile so that "make check" does
something reasonable in a tzdata-only (or tzcode-only) directory. However, that
would take some work and I don't see why the work would be needed, if the simple
suggestion works.
I would suggest at least the tzdata case should work standalone, as many distros
use only that, possibly with their own historical backward compatibility
customizations, and adapt or merge patches/selections from tzcode into their own
libc or bin code base (pkgs.org and repology.org have no hits for tzcode).
