log of make buildkernel

Here is the setting:

- a ZFS filesystem zroot/usr/src-stable is mounted at /usr/src and contains sources for 12-STABLE r348980;
- a ZFS filesystem /zroot/usr/obj/usr/src-stable is mounted at /usr/obj/usr/src-stable;
- the file /usr/obj/usr/src is a symlink to /usr/obj/usr/src-stable.

make buildkernel fails with the error message reported in the attachement.

It might be useful to know that this setting is the result of the following old setting:

- a ZFS filesystem zroot/usr/src-stable is mounted at /usr/src-stable and contains sources for 12-STABLE, whatever revision;
- a ZFS filesystem /zroot/usr/obj/usr/src-stable is mounted at /usr/obj/usr/src-stable.

Getting back to the old setting solves the problem, but of course we should try to get the new setting to work too.
Moreover, using the old setting, if a softlink /usr/src to /usr/src-stable is created, I can execute make buildkernel successfully both from /usr/src and /usr/src-stable. If I execute it from /usr/src, I can read lines such as "Building /usr/obj/usr/src-stable..."
