Huh. I've not come across lndir before, but we've got an opencoded
forms of it in several places. (tools/include, and
tools/firmware/xen-dir, maybe others.)
Still - as a build dependency, it should be the main xorg package, not
the *-dev{el} package. Whether a dev{el} package pulls in the main
package is distro-dependent.
4.15 is the oldest tree we test in Gitlab CI, and I don't believe we
built unmodified_drivers/ in prior versions either.
Either way - I don't think this alters the outcome of the patch. I can
add a paragraph to the commit message noting that there might have been
another unspecified dependency on xorg ?
