infinite 'make' recursion building Emacs

[Chris Moore]

I just tried building Emacs from CVS on my debian sid partition.  I
don't have a 'lispintro' directory, so the "(cd lispintro; make
info)" command failed to cd, but then ran 'make info' anyway.  As for
why this lead to an infinite recursion I don't know, but here's the
relevant part of the terminal output:

mkdir /usr/local/man
mkdir /usr/local/man/man1
(cd man; make  info)
make[1]: Entering directory `/mnt/breezy/home/chris/programs/emacs/man'
cd /home/chris/programs/emacs/man; makeinfo --force gnus.texi
cd /home/chris/programs/emacs/man; makeinfo --force pgg.texi
cd /home/chris/programs/emacs/man; makeinfo --force mh-e.texi
cd /home/chris/programs/emacs/man; makeinfo --force faq.texi
cd /home/chris/programs/emacs/man; makeinfo --force -D emacs tramp.texi
cd /home/chris/programs/emacs/man; makeinfo --force flymake.texi
make[1]: Leaving directory `/mnt/breezy/home/chris/programs/emacs/man'
(cd lispref; make  info)
make[1]: Entering directory `/mnt/breezy/home/chris/programs/emacs/lispref'
makeinfo --force -I. -I/home/chris/programs/emacs/lispref
/home/chris/programs/emacs/lispref/elisp.texi -o
/home/chris/programs/emacs/lispref/../info/elisp
make[1]: Leaving directory `/mnt/breezy/home/chris/programs/emacs/lispref'
(cd lispintro; make  info)
/bin/sh: line 0: cd: lispintro: No such file or directory
make[1]: Entering directory `/mnt/breezy/home/chris/programs/emacs'
(cd man; make -w info)
/bin/sh: line 0: cd: man: No such file or directory
make[2]: Entering directory `/mnt/breezy/home/chris/programs/emacs'
(cd man; make -w info)
/bin/sh: line 0: cd: man: No such file or directory
make[3]: Entering directory `/mnt/breezy/home/chris/programs/emacs'
(cd man; make -w info)
/bin/sh: line 0: cd: man: No such file or directory
make[4]: Entering directory `/mnt/breezy/home/chris/programs/emacs'
(cd man; make -w info)
/bin/sh: line 0: cd: man: No such file or directory
[...]

This kept going until I had around 600 make processes and the system
ground to a halt.
