Starting below this is wrong presuming all
builds are actually done on amd64:

Ending here.
This is written as if there were separate toolchains for
each target. That is not how llvm/clang/lld works,
unlike gcc. One toolchain covers all the targets. That
is what the FreBSD llvm support is structured for.
You want the one llvm/clang/lld toolchain that includes
everything required to build any/all of:
A) amd64
B) i386 for amd64's lib32
C) aarch64
D) armv7 for aarch64's lib32
So the *_LLVM_TARGET_* parts would be more like:
WITHOUT_PROFILE=yes
WITHOUT_TESTS=yes
WITHOUT_STATIC=yes
WITHOUT_LLVM_TARGET_ALL=yes
WITH_LLVM_TARGET_AARCH64=yes
WITH_LLVM_TARGET_X86=yes
WITH_LLVM_TARGET_AARCH64=yes
WITH_LLVM_TARGET_ARM=yes
So: outside the later conditional logic.
(Your REPODIR?= lines are identical and could also be factored
out of the conditional logic if they are not expected to be
independently changed. Only the KERNCONF?= lines are actually
target specific, needing to be in the conditional logic.)
