* Use mach_absolute_time() when clock_gettime() is not available. * Define MAP_ANONYMOUS to MAP_ANON if the latter is defined and the former is not. This matches what is done elsewhere in the code base in this situation, e.g. mmapmodule.c. * Don't build perf trampoline on ppc systems, where getting this to work would be a lot more effort.
