parallel-tests: more uses for '$(am__make_dryrun)' With this change we refactor some recipes of the parallel-tests harness to make them use, where appropriate, the new internal variable '$(am__make_dryrun)' (introduced in the 'maint' branch) when they need to determine whether make is running in "dry mode", i.e., with "make -n". This allows for some simplifications and for improved uniformity. * lib/am/check.am (check-TESTS recheck): Use $(am__make_dryrun) and simplify accordingly. (am--redo-logs): Delete this internal helper recipe, merged into ... ($(TEST_SUITE_LOG)): ... this, with the help of $(am__make_dryrun). recipe accordingly.
