  tests: quote 'like this', not `like this', as per GCS recommendation
  
  This patch converts the automake testsuite and related files, to
  the use of new quoting format 'like this' or "like this" rather
  than `like this'.
  
  This is done for consistency with the new recommendations in the GNU
  Coding Standards, and, well, because I've come to actually prefer
  the '...' and "..." quoting formats over the `...' one.
  
  * tests/README: Update quoting format throughout.  Remove some
  "excessive" use of quoting, and throw in minor rewording where
  appropriate.
  * tests/Makefile.am: Likewise, for comments.
  * tests/CheckListOfTests.am: Likewise.
  * tests/defs-static.in: Likewise.
  * tests/defs: Likewise.
  * tests/trivial-test-driver: Likewise.
  * Many tests/*.tap, tests/*.test and tests/*.sh files: Likewise,
  and for the diagnostic and informational messages as well.
  * tests/gen-testsuite-part: Likewise, and for the generated tests
  as well.

  # 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.
