Hello, could anyone tell me how you build NetBSD kernel for armv7?
Surely there is a way to build a kernel for BEAGLEBONE that doesn't
result in assembler errors?

How do you generate the following binaries:
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0.1/evbarm-earmv7hf/

I don't think I'm doing anything unreasonable

I've tried, removing all object files and running

/bin/sh ./build.sh -j 1 -u -m evbarm -a earmv7hf

and 

/bin/sh ./build.sh -j 1 -u -m evbearmv7hf-el

and both of them results in

--- vfp_init.o ---
