This fixes the problem 'nbconfig: cannot create /GENERIC'
when KERNOBJDIR has a relative path and is defined as env variable.
Problem reported and fix proposed on tech-toolchain@.

which does much of the same work but prints a result instead of
setting a global variable. Adjust the rebuildmake function to suit.
Improve the comments describing how we try to figure out whether
the existing tooldir make needs to be rebuilt.
Use getmakevar to expand MAKEOBJDIRPREFIX or MAKEOBJDIR, or (if
neither of those variables is set) use a non-recursive "make obj" in
the top level source directory.
* Do not let TOP_objdir default to ${TOP}. It's now set only by the
-M or -O command line options, or after using getmakevar to expand
MAKEOBJDIRPREFIX or MAKEOBJDIR.
* Make try_set_TOOLDIR handle MAKEOBJDIRPERFIX passed from the
environment. It runs too early to use getmakevar, so it will not work
if the value contains embedded '${...}' variable references.
* Use '$TOOLDIR' (with a literal '$') instead of 'nonexistent' in
a message when rebuilding make when TOOLDIR is not yet known.
is set to "yes" -- defaults to "no" except for build.sh builds. This
results in a deterministic .a file rather than one that reflects
timestamps and permissions on the source files.
Also, clean up the ar flags we're using, and remove a redundant use of
ranlib that on a modern POSIX ar can be done with the "s" flag.

prints something that does not look like an identifier, then use uname
-m instead. (Cygwin prints "unknown", and OpenBSD prints a long string
containing several spaces; this code should handle both.)

and store in the (non-exported) $TOP_objdir.
(We can't do the same for the environment $MAKEOBJDIR since it may contain
make(1) expressions that aren't easily parseable by sh(1))
Remember appropriate variations of '-M modp' and '-O mod' in $TOP_objdir
(replacing $makeobjdir misuse).
Use $TOP_objdir when trying to guess the TOOLDIR,
and when detecting if the top-level objdir needs to be created.
Fixes problems observed when testing fixes for PR 39360 and 39361.
Fix the TOOLDIR path used when guessing the TOOLDIR.

Use stricter result checking from make(1) when guessing the TOOLDIR.
PR 39361 from Andrew Cagney <cagney@gnu.org>
Apparently there are things you can do in the environment or mk.conf
to set your object directory in a way that the previous code couldn't
detect. (This is an interim measure until we can properly detect and
create the top level object directory in all cases.)
