If You have started the whole 'disaster' using 'make buildworld' then
all the necessary build-tools should still reside under /usr/obj/usr/src/tmp
or /usr/obj/usr/src/tmp/legacy including a statically linked clang. At least
this is the layout on 9.0-STABLE.

You can either setup your environment in single usermode to use these
(/usr/src/Makefile will give you some hints what to do) or copy them to
/usr/bin ...

Then try to rebuild and install your world (and kernel).


Hope this helps
