build failure on -current

When building current from git, I keep hitting the error below. This
is with meta-mode, but I've also tried deleting the object directory.
The system also has a couple of tweaks to src-env.conf that were an
attempt to avoid building any (most?) of clang. Relevant system
information:

$ uname -mrsv
FreeBSD 14.0-CURRENT FreeBSD 14.0-CURRENT main-22c4ab6cb0 GENERIC  amd64
$ cat /etc/src-env.conf
WITH_META_MODE=YES
WITHOUT_CLANG=YES
WITHOUT_CLANG_BOOTSTRAP=YES
$ env MAKEOBJDIRPREFIX=$(realpath ../obj) make buildworld -j$(sysctl -n hw.ncpu)
