  * automake.in (handle_lib_objects): Compute _DEPENDENCIES variables
  using transform_variable_recursively instead of
  variable_conditions_recursive and variable_value_as_list_recursive
  to avoid combinatorial explosion.
  (handle_lib_objects_cond): Merge into handle_lib_objects.
  * tests/cond11.test: Don't grep internal details in Makefile.in,
  run $MAKE to make sure the resulting Makefile runs as expected.
  * tests/cond29.test: Also exercise conditional _LDADD.
  * tests/cond31.test, tests/cond32.test: New files.
  * tests/Makefile.am (TESTS): Add tests/cond31.test and
  tests/cond32.test.

  # On this test, Automake 1.7.x would compute all 2**22 = 4194304 possible
  # combinations of conditionals (it would do this three times, to define
  # a01_DEPENDENCIES, a02_DEPENDENCIES, and to rewrite bin_PROGRAM), eating
  # all memory, swap, or cpu time it can found.  Although this test won't 
  # print `FAIL' if it fails, it will take long enough so it can't go unnoticed.
