Changed, again, RDTSC and Hardware counter, introducing auto calibration when hardware counter is too slow for modern standard (and removed BOX64_RDTSC env. var.)

-#### BOX64_RDTSC *

-Will use time-based emulation for rdtsc, even if hardware counter are available. Tick rate of Hardware counter (like on Arm64) might be too low for accurate RDTSC emulation.

- * 0 : Use hardware counter if available (depend on architecture basicaly)

- * 1 : Use monotonic timer to emulate rdtsc

- * 2 : Check frequency of the hardware time (if present), and use hardware if frequency is 1GHz or better or else use mono-tonique time.

 #### BOX64_X11GLX *

 Force libX11's GLX extension to be present.
