I've hit an unexpected delay - my main system has been updated from
netbsd-9 to -10 since we started testing, and the gcc-10 in netbsd-10
will not directly compile the older NetBSD release. I'm just building
gcc-7 on my box to see if I can use that to bootstrap the cross
compiler instead, otherwise I'll have to setup a netbsd-9 VM to build.
Nothing critical - just means it will take a little longer to get
setup to crank through building some more test kernels
