texinfo 4.7 build problem on Solaris 8, due to $< in Makefiles

[Paul Eggert]

I had the following problem building texinfo 4.7 on Solaris 8, using
Solaris "make":

   Making all in util
   ...
   gcc  -g -O2   -o texindex  texindex.o ../lib/libtxi.a 
/opt/reb/lib/libintl.so -L/opt/reb/lib /opt/reb/lib/libiconv.so -lc 
-R/opt/reb/lib -R/opt/reb/lib/gcc/gcc-3.3.2/lib 
   sed 's/__VERSION__/4.7/g'  >texinfo.cat

At this point the build hung, because sed was reading from my
terminal.  The problem is that Texinfo sometimes uses "$<" in ordinary
"make" rules; this isn't portable.  I noticed a similar instances of
this in doc/Makefile.am.  Here's a patch for both.

        * doc/Makefile.am (info.1, infokey.1, install-info.1,
        makeinfo.1, texi2dvi.1, texindex.1): Don't use $< in ordinary
        rules; it's not portable.
        * util/Makefile.am (texinfo.cat): Likewise.
