which fails the make tests (doesn't understand ${notdef:U}) and therefore
fails on __FBSDID in usr.bin/make/*. -DBOOTSTRAPPING is no help here since
this is before we are using the new share/mk/* files, and it would conflict
with the builtin -DBOOTSTRAPPING support later.. so use a different flag.

parsing the argument for getopt(3).

we use in sublte ways with relative paths. Until they can be resolved,
back out these changes and put a big comment about why using realpath is
busted.

seen (somewhat) in NetBSD. This catches a few extra recursion cases that
could be hidden by expanding a NIL variable causing an existing variable to
be returned (which caused infinite looping and climbing memory usage in at
least one case).

When merged, this will be used to replace the ugly upgrade_checks

it, which means that relative paths will be expanded to absolute paths, and
filenames without a path will end up with their absolute path included as
well. This aids tremendously in debugging a build using our make(1) with
multiple Makefile's, such as when there is a syntax error in a file in a
sub-directory as per <bsd.subdir.mk>. Normally we'd end up with just
"Makefile" known about the Makefile in question, which means that an error
would be useless for someone trying to debug their build system, now we
end up with a complete real pathname for the Makefile.
So mostly this is useful in a debugging context, but possibly others too
(I haven't thought of them yet, but they probably are more useful if you
make Dir_FindFile use realpath(3), but that's another story).

With rev 1.7 one cannot build src/bin/sh -- because make fails to create
the buildtools before trying to use them. Actually it does compile the
buildtools into .o's before trying to use them, but not all the way into
binaries.

The problem seems to be that in str_concat(), the string is not
terminated when the length of the second string is 0.
This apparently can happen during null suffix rule processing.
