but not to track it - as is done for .export
This allows the variable to be updated without affecting what was put
into the environment.
Older versions of make will simply treat this as .export
realpath(3). Consider: touch Makefile; mkdir make; make. This will set $MAKE
to $PWD/make so further attempts to use ${MAKE} will try to execute the
directory. This needs $ORIGIN to be fixed properly, or alternatively one
can duplicate the logic for execvp(3) and search the path for the make
executable. Not worth it. It was working just fine before!

We need to check both to ensure that on SunOS signal is hooked into
sigaction - otherwise we do not pass the unit-tests due to missing
a SIGCHLD

Can put make into "compat" mode (more to come).
Fix:
compat.c: Error code should not be sent to debug_file.
Make_DoAllVar: use DONE_ALLSRC to avoid processing a node multiple times.
ReadMakefile: we can simply use doing_depend to control setting MAKEFILE.

for substitution patterns. This (perhaps coupled with the
new handling of .for variables in ${:U<value>...) caused interesting
results for lines like:
.for file in ${LIST}
for-subst: ${file:S;^;${here}/;g}
add a unit-test to keep an eye on this.
Use .MAKE.LEVEL to track recursion.
The first instance of make will have .MAKE.LEVEL 0, which
can be handy for excluding rules which should not apply
in a sub-make.
gmake and freebsd's make have a similar mechanism, but each
uses a different variable to track it. Since we cannot be
compatible with both, we allow the makefiles to cope if they want
by handling the export of .MAKE.LEVEL+1 in Var_Set().
