All the errors seem related to the old Rune size. I suspect you're running
an old system and it's likely to not have nsec and tsemacquire syscalls
either.

If you believe the system is up-to-date, you can cross compile a simple Go
program using 1.5 or later targeting GOOS=plan9 GOARCH=386 from a Linux/OSX
or Windows box and see if it runs on your system.  That might give you more
info.
