    newlib: Enable automake silent rules
    Use AM_SILENT_RULES, to enable automake silent rules (by default), if we
    are using a version of automake which supports it (>=1.11).
    Silent rules can be disabled by configuring with '--disable-silent-rules',
    or invoking 'make V=1'.
    For ease of reviewing, this patch doesn't contain configure and regeneration.
    Future work: There are a few compilations which are not silenced by
    this, as they use custom rules.
