If you work on this then please have a look at PR 247519, too:

	https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247519

This problem lead to my complete customized /etc getting lost when I
invoked etcupdate with WITH_DIRDEPS_BUILD defined in /etc/src-env.conf.

But I can imagine other reasons that let the make commands in build_tree()
fail without error exit, leading to an empty etcupdate/current tree and
subsequent deletion of files in /etc.
