	Christos' latest round of changes to make(1) seem to have
	broken something.  When doing a "make -j8 clean" in /usr/pkgsrc,
	I see:

icky:thorpej 146$ sudo make -j8 clean     
--- clean ---
===> archivers
Segmentation fault - core dumped
*** Error code 139
1 error
icky:thorpej 147$ 

	Quick examination with gdb reveals:

icky:thorpej 21$ sudo gdb obj.i386/make /usr/pkgsrc/archivers/make.core

391             buf = emalloc(strlen(line) + strlen(argv0) + 2);
(gdb) print argv0
$1 = 0x0

	`argv0' is initialized at the top of that function as:

        char *argv0 = Var_Value(".MAKE", VAR_GLOBAL, &p1);

	See above.

	Unknown.  (I don't want to get to know make(1) that well,
