Enable silent build rules by default

Enable silent build rules by default.

You can still use verbose build rules by using any of the following
methods:

  * run "configure" with the "--disable-silent-rules" argument
  * run "make" with the "V=1" argument

Not all make recipes have been converted to be silent, but the
majority are standard recipes which are now silent.
