Seems I didn't send email to GNATS about this build issue, so here's a
final update:

  * As it turns out, the (full path and) filenames of libc sources
    turn up in the ramdisk's multicall binary. The ramdisk is tight
    for sun2, so this broke with my setup (Linux host, CI builds not
    /usr/src, but similar to
    /var/lib/laminar/run/4/netbsd-sun2-m68000/NetBSD-src/ . The
    additional binary size made the ramdisk go out of free space.

  * Christos suggested to just build it as a reproducible build, as
    that should cut down my long pathes to /usr/src. This failed, the
    long pathes kept showing up, breaking ramdisk creation.

  * Turned out: GCC's path remapping code accidentally got merged out.
    Unfortunately, the reproducibility checking scripts didn't catch
    that, was both reference builds were done from the same directory.

  * Christos reinstated the GCC patch and sun2 now builds for me as
    well, with the long pathes properly substituted.
