x86intrin.h is gcc own header file (I had to patch time.h to avoid
build problems fir libstdc++-v3: both time.h and ia32intrin.h included from
x86intrin.h define _rdtsc and later as a macro and one can imagine
results)

The problem is that when building DJGPP libc GCC own headers are
currently not included at all.

- we could only put DJGPP own include directory first in search path and not to
   disable other ones
- we could append GCC header directory to the include directories and disable others

Unfortunately did not think about that earlier.
