BSD make and '$<'

[kunihiro@xxxxxxxxx]

Using BSD make (I use one coming with FreeBSD), there is problem
around '$<' in Doc/Makefile.in.  But there is no problem making with
GNU make.

Dose anybody know BSD make thinking '$<' should be used always with
implicit rule?  I'm not sure...

% cd zsh-3.0-pre4/Doc
% make -n
makeinfo -I.

% gmake -n
makeinfo -I. zsh.texi

Hmm.  I fixed it like this.
