win32: fix compilation again

While commit c02817e5 fixed compilation
without an installed libtool, moving the dependencies to rules.mak does
not work because the version-*-y variables are not defined yet.  Building
in a clean tree thus fails.

Revert the commit and remove the dummy /bin/false assignment to LIBTOOL.
This makes the build work, at the price of slightly worse errors when
there are Makefile bugs.
