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.
Okay, WITHOUT_WERROR did help, obviously.
But then I got another problem related to the use of -flto in usr.bin/gh-bc.
It caused .o files to be LLVM IR bitcode instead of "normal" object files.
My best guess now is that my combination of WITHOUT_CLANG and
WITH_LLVM_TARGET_X86 causes a wrong (host) compiler to be used in the build.
My goal with those flags was to not build clang/llvm for the target, but to have
them for the correct cross-build. But apparently the flags do not do that (any
longer).
What's interesting is that I saw this during the build (make with -s option):

Trying now a build with WITHOUT_CLANG (as before) but without
WITH_LLVM_TARGET_X86.
