  tests: make tests behave for the AR=lib case
  
  These below tests were left mostly as-is when AM_PROG_AR was
  introduced (with libobj16b being the exception, that test was
  forgotten or has regressed since), in a misguided attempt to
  not make them diverge from the original problem reports.
  
  Modernize them so that they do not FAIL when $AR is Microsoft
  'lib'.
  
  * tests/libobj16b.test: Add AM_PROG_AR to configure.ac and remove
  the no-longer-needed -Wno-extra-portability option when invoking
  automake.
  * tests/pr300-lib.test: Likewise.
  * tests/pr300-ltlib.test: Likewise.
  * tests/pr307.test: Likewise.
  * tests/pr401.test: Likewise.  Also fetch the 'ar-lib' script.
  * tests/pr401b.test: Likewise.
  * tests/pr401c.test: Likewise.

  # Test for PR 307: depcomp with depmode=dashmstdout libtool race condition
  # Report from Laurent Morichetti.
  # (Also exercises check_LTLIBRARIES.)
  #
  # == Report ==
  #  The dashmstdout depmode calls libtool in parallel to generate the
  #  dependencies (with -M flag) and to build the objfile (both have
  #  --mode=compile and -o).
  #  The process with 'libtool --mode=compile .* -M' can corrupt the objfile
  #  as none is generated by the compiler.  Since --mode=compile and -o are
  #  set libtool assumes that a objfile should be generated and will execute
  #  invalid $mv & $LN_S.
  #
  # == Fix ==
  #  Now 'depcomp' never compute dependencies in the background, as this can
  #  cause races with libtool.  Compute the dependencies after the actual
  #  compilation.
