some NUMA related syscalls: mbind, get_mempolicy are not supported on
some arches (e.g. i386), this patch checks the syscalls' availability in
setup() function, if the syscall is not implemented on the system, a
TCONF message will be given like this:

get_mempolicy01    1  TCONF  : syscall __NR_get_mempolicy01 not supported on your arch
