My suggestion would be to test $LD == ld and then use LD=ld.lld with a comment
about the reason but my makefile syntax knowledge is limited.

I would be happy with expanding the error that is emitted by
pre.mk to add the text "You can fix this with LD=ld.lld make ..."
and an entry in UPDATING that specifically says for 12.0 on i386 you need...

Yes, the problem is that ?= only works once. There's some gross things we
can do, but they aren't worthwhile, imho.
eg
.if defined(KERNEL_LD_OVERRIDE)
LD=${KERNEL_LD_OVERRIDE}
.else
LD=ld.lld
.endif
or other variations on that. We could do it without the .else clause and
just add KERNEL_LD_OVERRIDE=ld.lld to GENERIC on i386 as a build-time
override. This would give people a way out, but would violate POLA a little
bit. Given the frequency of overriding LD=, it may be OK. People
sophisticated enough to do that surely are sophisticated enough to read
changes to the kernel config files. This wouldn't help everybody
(especially those with custom kernel configs), but short of adding it to
DEFAULTS, it's likely pushing the edge of how disruptive one can be in a
stable branch.
So there's a number of variations on this theme. I'm not convinced they are
worthwhile for this issue because none are side-effect free, but it's
certainly a solution space others can noodle through to see if they can
find the "just so" mix of POLA and bug fixing.

Let me guess. You use 'make' in sys/i386/build/YOUR_KERNEL ?
Then you need to use 'LD=ld.ldd make'. The proper way of
'make buildkernel' from top-level src handles it automatically.

Sadly I have confirmed that "make kernel-toolchain" does infact
fix the above error.
Now the begging question, why isnt the toolchain as shipped
already properly built?
This is a stock FreeBSD-12.0=RELEASE-i386-disc1.iso install,
with stock sources from the iso. I was simply configuring
a custom kernel, I should not need to build a took chain
to build a kernel when nothing has changed from the
RELEASE, it should already be the correct toolchain.

This is the -RELEASE, why is the release not built with the
proper toolchain in place? This is not some upgrade or anything
odd, download 12.0-RELEASE i386 iso, install it with sources,
try to build a kernel.
I am running your suggested make kernel-toolchain now
to see if that fixes the problem (it shouid not, or
if it does we have a major issue with our release
building procedures.)

After ifunc support was introduced, you have to run at least
"make kernel-toolchain" before "make buildkernel", or otherwise just run
"make buildworld" first. That will build the linker which supports the
required functionality.

I typically build kernels without doing "make buildkernel" and I've found I need
LD=lld SRCTOP= on the make commands.
(or something close to that. I haven't done this since December.)
I haven't tried, but I assumed "make buildkernel" takes care of this "behind the
curtains".
