If we define own _rdtsc() we get duplicate definition of it when GCC own header x86intrin.h is also
included (for new GCC version). That was the reason why I used GCC defined function instead
of DJGPP one.

There is additional problem that GCC header files *intrin.h are not OK when -Wcast-qual is being used.
The problem is triggered when building DJGPP tests but not when building libc itself.
