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().
