_LP64 is commonly defined by the platforms/compilers.
_XSERVER64 was our own invention before that became a defacto standard,
there used to be a monster if (__IA64__) || (__sparcv9__) || ... (every
other 64-bit RISC CPU) to decide if it should be #defined.
Now we have in include/xorg-server.h:
#ifdef _LP64
#define _XSERVER64 1
#endif
