You mean with "make target buildwork", that you are running "make
buildworld TARGET=whatever", right?

Most likely, this is because you are forcing CC=clang, which does not
work as expected.  Can you please post your /etc/make.conf and
/etc/src.conf files, and show us any environment variables related to
buildworld?  Also, how exactly are you running make buildworld?
