Fix DisjConditions module to be thread-safe for perl >= 5.7.2. Self-hashes of blessed references are not correctly transported through thread creation. This patch fixes that by recreating the hashes upon thread creation with a CLONE special subroutine, which is automatically invoked by new enough Perl versions. * lib/Automake/DisjConditions.pm (CLONE): New special subroutine to fix self hashes upon thread creation. * lib/Automake/tests/Condition-t.pl: New, sister test to Condition.pl, but spawns a new threads after each creation of a new condition; skip test if perl is too old or ithreads are not available. * lib/Automake/tests/DisjConditions-t.pl: Likewise. * lib/Automake/tests/Makefile.am (TESTS): Add them.
