Recent tries at a custom kernel for Pi2 and Pi3 are mixed. Pi2 seems to
work fairly well, but the size reduction isn't impressive.
The latest try with a Pi3 kernel stopped with

Compilation was from a clean start, beginning with make -j1 kernel-toolchain.
I re-ran svnlite update but didn't see any relevant changes and a retry
failed as before. I also tried, on a whim
cp /usr/lib/include/stdint.h /usr/obj/usr/src/arm64.aarch64/tmp/usr/include/
just in case it might help, no difference (not surprising, the file, which
used to be missing after make kernl-toolchain, apparently wasn't).
The kernel config is at
http://www.zefox.net/~fbsd/rpi3/kernel_config/ZEFOX
if anybody would take a look for errors. It was ok as of
r329893
Thanks for reading!
