  parallel-tests: fix another BSD parallel make issue
  
  When BSD make is run in parallel mode, it apparently strips any
  leading directory component from the automatic variable '$*' (of
  course, against what POSIX mandates).  This was causing FreeBSD 9.0
  make and NetBSD 5.1 make to spuriously fail with automake-generated
  test harnesses if subdir tests were present *and* make was being
  run in parallel mode.  This issue affected also the Automake own
  testsuite.
  
  * lib/am/check2.am (am__set_b): New internal variable.
  (%OBJ%, %EXT%.log, %EXT%$(EXEEXT).log): Use it to work around
  the described BSD make issue.
  * tests/parallel-tests3.test: Enhanced to expose the bug.
  * tests/parallel-tests-subdir.test: Enhance a little, since we
  are at it.
  * NEWS: Update.
