parallel-tests: optimize 'recheck' target for speed With this change, the time required to execute the test case 'testsuite-recheck-speed.sh' has dropped as follows: + Slow Debian i686 system, 1 core x 1.5 GHz, 768 MB of RAM, GNU make 3.81: - 1 run: 6 minutes => 40 seconds + Fast Solaris 10 i686 system, 4 cores x 3 GHz, 20 GB of RAM, Solaris CCS make: - 4 runs: 3 minutes => 1 minute + Very fast Fedora ppc64 system, 64 cores x 3.5 GHz, 64 GB of RAM, GNU make 3.82: - 5 runs: 4 minutes => 1 minute 30 seconds * lib/am/check.am (recheck): Optimize for speed, by avoiding lots of forks with the help of ... (am__list_recheck_tests): ... this new internal variable, basically defining a proper awk program, and ... (am__recheck_rx): ... this other new internal variable, used by the one above. * t/test-trs-recover2.sh: Relax by not checking for a very corner case ('.log' and '.trs' files both unreadable) that we don't handle anymore.
