Use silent-rules for building the Automake package.

[Ralf Wildenhues]

Pushed to master.

Cheers,
Ralf

    Use silent-rules for building the Automake package.
    
    * configure.ac (AM_INIT_AUTOMAKE): Add silent-rules option.
    * Makefile.am (automake, aclocal, INSTALL): Add silencing
    variables to recipe.
    * doc/Makefile.am (update_mans, $(srcdir)/aclocal.1)
    ($(srcdir)/automake.1, $(srcdir)/amhello-1.0.tar.gz): Likewise.
    * lib/Automake/Makefile.am (Config.pm): Likewise.
    * tests/Makefile.am ($(srcdir)/parallel-tests.am)
    ($(parallel_tests), defs-p): Likewise.
