bootstrap: show output from 'make bootstrap-deps'.

* bootstrap.conf (libtool_build_prerequisites): Add support for
AM_V_GEN and AM_V_at to the temporary pre-configure Makefile.
Instead of eliding non-error output from bootstrap-deps, show
the results, with verbosity set according to $opt_verbose.
* Makefile.am (m4/ltversion.m4, build-aux/ltmain.sh, libtool)
(README): Fix the display rules to correctly fall-back to
AM_DEFAULT_VERBOSITY when V=1 is not passed to make invocation.
