Tried it, like so:
root@www:/usr/src # make -j4 buildworld TARGET_ARCH=armv7 > buildworld.log &    [1] 1006
root@www:/usr/src # 1 error

[1]    Exit 2                        make -j4 buildworld TARGET_ARCH=armv7 > buildworld.log
root@www:/usr/src # more *.log
--- buildworld ---
make[1]: "/usr/src/Makefile.inc1" line 450: To cross-build, set TARGET_ARCH.
*** [buildworld] Error code 1

make: stopped in /usr/src

I also tried setting TARGET=arm and WITHOUT_SYSTEM_COMPILER=yes in various
iterations. Should the variables be set somewhere else, in a config file?

At this point the kernel is at r324499, along with the sources. Userland
dates from late June (operator error). Kernels build, but could that make
the trouble I'm seeing? Clang -v reports 

FreeBSD clang version 4.0.0 (tags/RELEASE_400/final 297347) (based on LLVM 4.0.0)
Target: armv6-unknown-freebsd12.0-gnueabihf
Thread model: posix
InstalledDir: /usr/bin

Thanks again!
