Ok. I'm hopefully going to check that out the next days if time permits.

Btw, the line in compat_netbsd32(8) is wrong (or maybe not the only 
possibility):

arm64        eabi       /usr/libexec/ld.elf_so-eabi

According to ktrace it should be /usr/libexec/ld.elf_so-evbarm.

My 32bit target is "-m evbarm -a earmv7hfeb" (build.sh parameters).
