  tests: prefer including 'test-init.sh' rather than './defs'
  
  This is a follow-up to today's commit v1.12.4-22-g0610fc8,
  "tests: prepare to move ./defs to t/ax/test-init.sh"
  
  * All tests: To run the common setup, use the command:
  
      . test-init.sh
  
  instead of the older, "historical" one:
  
      . ./defs || exit 1
  
  Note that the "|| exit 1" wasn't really useful, since the 'errexit'
  shell flag is in effect in both './defs' and 'test-init.sh', and all
  the known shells that are good enough to run the automake testsuite
  do automatically exit with error when a sourced file cannot be found
  (at least, they do so in non-interactive mode, which is the only
  mode that concerns us in the testsuite).
  
  * t/ax/tap-summary-aux.sh, t/ax/testsuite-summary-checks.sh: Likewise.
  
  * gen-testsuite-part: Do the same in the generated tests.

  # 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.
