Re: make bootstrap fails.

>From my earlier reply:
   
   Moreover, other Makefiles, for instance the texinfo-4.6
   Makefile use their own CDPATH (they do not just unset CDPATH) even
   though they use /bin/sh.

I said something inaccurate here: it locally sets CDPATH for one
particular command (am_cd).  But the point remains the same.  That
command is executed by /bin/sh.

Sincerely,
