----------------------+-----------------------------------------------------
 When building the ET on Ubuntu 16.04, the PETSc external library fails
 during configuration.  The error, from configure.log, is
 {{{
 Possible ERROR while running archiver:
 stderr:
 /usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')
       Archiver is not functional
 *******************************************************************************
          UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for
 details):
 -------------------------------------------------------------------------------
 You set a value for --with-ar=ar", but ar cannot be used
 *******************************************************************************
 }}}
 Setting this as critical for the upcoming release, since people will
 likely want to build the ET on their Ubuntu 16.04 machines.
