This patch handles compiles with threads, namely if you don't have pthreads it will remove support for threads in the applications (and it is fixed in such a way that tests won't break).


client/mysqlimport.c:
  Add in flags to support compiles with no thread support.
client/mysqlslap.c:
  Add support to source code to compile without threads.
