Are you skipping any toolchain bootstrap steps? I tried building releng/14.2

AFAIK, no.
This is 'make buildworld' after blowing away /usr/obj.
That said, from your original message it looks like it's a -Werror warning, so
you could try using WITHOUT_WERROR?
I can try that for sure.
Thisn is definitely something unexpected as I've recently built stable/14 on the
same host without any issues.
Just in case, a fuller error message from a -j1 build:
===> lib/libdevdctl (all)

Oh, and probably something that I should have mentioned (and recalled myself)
from the start. This is a build for a disk-constrained system, so it have these
in its src.conf:
WITHOUT_CLANG=yes
WITH_LLVM_TARGET_X86=yes # to undo effect of WITHOUT_CLANG
I am not sure where i picked up those, but I suspect that this kind of muckery
with the toolchain can result in problems.
