Bugs in installing...

Ok, here is the problem: we should really fix the tarball in a way
that if ./configure does not find either Perl or makeinfo, the
build/install will _NOT_ change any files (most of that job probably
can be done by replacing the executable with ":" in the Makefile
variables, as long as they are not used in commands with >something
but rather with -outputfile something).

That means, of course, that the documentation should be part of the
tarball.

Does somebody volunteer for a "tarball-ready" or "bootstrap" or
similar target in Makefile.in of preview-latex and appropriate changes
for dealing with missing or outdated makeinfo or Perl in configure.in?
The Makefile target should probably also do most things currently done
by ./autogen.sh.
