[PATCH] Fix autom4te.cfg problem with reconfiguring

[Paolo Bonzini]

These commands

        ./configure --prefix=/usr/local
        make
        ./configure --prefix=/usr
        make
        make install

produce an unusable autoconf because autom4te.cfg is
not rebuilt.  Yes, one should do a make distclean just to
be sure, but since the cure is as easy as mentioning
Makefile in the dependencies of autom4te.cfg like
bin/Makefile.am does, I propose this patch:

        * lib/Makefile.am: make autom4te.cfg depend on
        Makefile since it contains substitutions
