netbsd-9 failure

[John Klos <john%ziaspace.com@localhost>]

Is this a known issue? Ignoring lots of:

gawk: cmd. line:4: warning: regexp escape sequence `\"' is not a known regexp operator

which is due to gawk being used instead of the system awk (which I thought 
was fixed ages ago), compiling netbsd-9 tools for earmv6hf from today 
fails:

./build.sh -D ../dest-evbarm -O ../obj-evbarm -T ../tools -R ../sets -m evbarm -a earmv6hf tools
