No, because 'libtool' is created in the build tree, and the manpages are
distributed.  Distributed files may not depend on undistributed files,
as that breaks building from a read-only source tree.  Moreover,
help2man is something the user is expected to not have to install prior
to building Libtool.

Cheers,
Ralf
