parallel make bug

With make -j2, after bin/autom4te.in has been edited, I got this failure:

/bin/sh: ../bin/autom4te: No such file or directory
make[1]: *** [autoconf.in] Error 127
make[1]: *** Waiting for unfinished jobs....

Is this patch correct for installation?  I tested with an in-tree build,
so I'm a bit worried that I may have missed a VPATH subtlety.

        * bin/Makefile.am (autoconf.in): Depend on autom4te.

Don't work too hard, make some time for fun as well!
