The 2026-10-07 nightly ships the same six compatibility libraries with
their full versioned file names beside the short ones (libXss.so.1.0.0),
and two under their GTK 3 names (libappindicator3, libindicator3). The
guard in package() listed the short names only, so it stopped the build
on both architectures and with it the bundled upstream sync (#837).
Accept an optional 3 and trailing version numbers. Anything else in
usr/ still stops the build. t3code-bin carries the same guard and gets
the same pattern before the change reaches a stable release.
