build.sh of tools (nbhost-mkdep) fails on i386 vm

[yancm%SDF.ORG@localhost]

I'm following up again with more detail, this first one is what I  am
seeing when I try to build tools. I've been building successfully  for
several years, so was kind of stumped when this started happening  a
couple of weeks ago...even more curious that it seem localized to me.

After a fresh cvs update from current and deleting /usr/obj and
/usr/tools...

on my vm name xperiment...
