Ah, yes...  agreed.

The tools in $TOOLDIR can and should be owned by the builder.

METALOG is, as far as I can tell, never needed for the installation of
the tools.

If I'd have kept one....  :-(

The host system didn't include the custom changed header file.

The build system really should be expected to work properly with this
kind of change since it wasn't using the host system's headers but
rather the headers installed in $DESTDIR/include.

Remember that regardless of what change I actually made and which module
encountered an error because of it, the overall affect was that
"./build.sh -u" didn't work, and it didn't work because the fixed header
was not re-installed during the "./build.sh -u" run.  What did work was
manually re-doing the "includes" step.

(and just to repeat what was obvious from my initial post but what may
have been lost since by the abbreviation of my example commands:  I am
NOT using "-D /", and indeed I am doing unprivileged builds as I would
never think to do anything else :-)

I've since made the following change and have redone a full build and
several update builds with no problem, at least not for a netbsd hosted
build (where the native install and mkdep commands are sufficient for
building and installing the toools into TOOLDIR).
