Set numThreads to 1 by default when Python is older than 2.5.2.
Python 2.4 always hits this bug: http://bugs.python.org/issue1731717 when running check-lit on multi-core systems. Setting numThreads to 1 makes it slower, but at least the results reported are correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98969 91177308-0d34-0410-b5e6-96231b3b80d8
