* harbour/src/3rd/pcre/Makefile
    * disabled JIT support in default builds.
      It fixes build process for platforms which do not support MT mode
      like some old Linux distors. I also made runtime tests with some
      simple expressions and on x86 based CPUs the difference is really
      minor. PCRE compiled with JIT is a little bit faster in regex
      compilation (~5%) but slower in regex evaluation (10%).
      AFAIR completely different results then suggested by documentation.
      For tests I used rather simple expression on small data set:
         cData := hb_TSToStr( hb_datetime() )
         cExp := "[:]([a-zA-Z]|[0-9])[0-9][:]..[.]"
      But such short expressions and data are quite common in real
      programs.
      If someone wants to enable JIT in his build then he can make it
      using SUPPORT_JIT macro, i.e.:
         export HB_USER_CFLAGS=-DSUPPORT_JIT
