[svn-r26081] Moved the check for pthread_attr_setscope() into the thread-safe checks
section. Documented its necessity and added a cross-compiling option and helpful comment. Also removed a check for BSDgettimeofday from configure.ac, which was for Irix 5.3 support. Part of HDFFV-9087 Tested on: jam with threadsafe
