I think it is related to something going wrong with
the script that updates submodules, which fails to
actually pull in the submodule code for dtc etc.
This bug is triggered because the configure script adds
"slirp" to the list of submodules even though it is not
actually a submodule. Dan was looking at this a few days
back, IIRC.

We should fix the update script to be more robust to
being asked to update nonexistent submodules, but
we should also stop asking it to do anything with
the nonexistent 'slirp' submodule...
