Ok, thanks. Another diff is we're using fixincludes for vx6
(not 7), and have a local patch setting sysroot_headers_dir in
a particular fashion to handle kernel vs rtp (part of what I was
intending to propagate as well). We're not using --sysroot directly.

I'll check how our build sequence proceeds.
