Failed to startx, I think I've broken something there. But that was
supposed to be a "generic" build (the sort I should be able to copy
to a new machine, fix up the kernel, and use to boot a new LFS) and
I'd accidentally left -march=native in the glibc build. So, I'm
doing a fresh build of that system, with myself in the wheel group.

What are you suggesting I should do differently in recompiling
elogind ? I've already compiled dbus for a first time, elogind,
xtrans and the rest of the xorg libs, dbus again, the usual stuff
including pixman, libdrm, Mesa, some xorg apps, polkit with its
deps, and then xorg-server.
I appreciate you haven't read the whole set of threads/subthreads,
so may I post soemthing I wrote earlier (reformatted) ?
From /usr/share/polkit-1/actions/org.freedesktop.login1.policy

Please note that this authentication is auth_admin_keep. From
https://www.freedesktop.org/software/polkit/docs/latest/polkit.8.html
auth_admin
Authentication by an administrative user is required.
[...]
auth_admin_keep
Like auth_admin but the authorization is kept for a brief period (e.g. five
minutes).
That is why I think being an administrative user is required.
