  silent rules: support for them is always active now
  
  Before this change, support for silent rules was optional and activated
  only if the 'silent-rules' option was specified.
  
  The rationale behind that behaviour was that the silent-rules machinery
  originally only worked with make implementations supporting nested
  variables expansions, which isn't (or wasn't) a POSIX-specified features;
  so that packages wanting to be "extra-portable" couldn't use the
  silent-rules machinery at all.
  
  But after Paul Eggert's commit 'v1.11-598-g8493499' of 25-12-2011,
  "silent-rules: fallback for makes without nested vars" (motivated
  by automake bugs #9928 and #10237), Makefiles generated when the
  'silent-rules' option is enabled can work also with those make
  implementations that don't support nested variables expansion (albeit
  the configure-time selected verbosity cannot be overridden at make
  runtime in such case).
  
  In light of that, and since silent rules are disabled by default even
  when the 'silent-rules' option is given (unless the developer explicitly
  makes them enabled by default be calling "AM_SILENT_RULES([yes])" in
  configure.ac), we can now have the support for silent rules always
  enabled.
  
  The 'silent-rules' option will thus become a no-op, but will reaming a
  valid option for the time being, for better backward-compatibility.
  
  A collateral effect of this change is that the use of the 'silent-rules'
  option will not anymore automatically disable the warnings in the
  'portability-recursive' category.
  
  The present change is basically a backport of the Automake-NG commit
  'v1.11d-75-g61ca923' of 19-04-2012, "[ng] silent rules: support for
  them is always active now".  Stemmed by this thread on the Automake-NG
  list:
  <http://lists.gnu.org/archive/html/automake-ng/2012-04/msg00027.html>
  
  * automake.in: Enable silent-rules machinery unconditionally.  Reword
  some comments.  Do not switch off warnings in the category
  'portability-recursive' anymore if the 'silent-rules' option is
  given.
  * m4/init.m4: Call 'AC_REQUIRE' on 'AM_SILENT_RULES' unconditionally.
  * lib/Automake/Options.pm: Recognize 'silent-rules' as a dummy option.
  Do not bother anymore checking that it is set in 'configure.ac'.
  * t/silent.sh: Remove now-redundant calls to AM_SILENT_RULES.
  * t/silent2.sh: Likewise.
  * t/silent3.sh: Likewise.
  * t/silent4.sh: Likewise.
  * t/silent8.sh: Likewise.
  * t/silent9.sh: Likewise.
  * t/silent-lex.sh: Likewise.
  * t/silent-many-gcc.sh: Likewise.
  * t/silent-many-generic.sh: Likewise.
  * t/silent-yacc-headers.sh: Likewise.
  * t/silent-yacc.sh: Likewise.
  * t/silentcxx-gcc.sh: Likewise.
  * t/silentcxx.sh: Likewise.
  * t/silentf77.sh: Likewise.
  * t/silentf90.sh: Likewise.
  * t/help-silent.sh: Likewise.
  * t/silent-configsite.sh: Likewise, and other minor adjustments.
  * t/silent7.sh: Likewise.  Also, extend to check that silent rules
  are disabled by default, and remove obsoleted checks about the
  'silent-rules' option being rejected in 'AUTOMAKE_OPTIONS'.
  * t/silent6.sh: Remove now-redundant calls to 'AM_SILENT_RULES'.
  Call automake with '-Wno-portability-recursive'.  Remove other
  obsoleted checks.
  * t/dollarvar.sh: Don't expect the use of 'AM_SILENT_RULES' in
  'configure.ac' to disable warning in the 'portability-recursive'
  category anymore.
  * t/compile_f_c_cxx.sh: Adjust to avoid a spurious failure.
  * t/silent-amopts.sh: Remove as obsolete.
  * t/silent-nowarn.sh: Likewise.
  * t/list-of-tests.mk: Adjust.
  * NEWS: Update.
  * doc/automake.texi: Update and simplify accordingly.
  * configure.ac (AM_INIT_AUTOMAKE): Remove 'silent-rules' option.
