I think this will take some additional investigation.  Looking through
the musl code, there is some amount of support for utmp, wtmp, and
lastlog, although I've not looked at enough to actually understand what
it provides or implements.

Possibly disabling utmp/wtmp in busybox is not actually needed, but I'm
not sure yet.  So I've created a trac ticket: http://trac.clfs.org/ticket/1160

Thanks,
Andrew
