I don't know how significant this is (most of the NUMA node data seems
unused at this point), but anyway: enable proper operation of NUMA
emulation and the fake NUMA node in case there's no SRAT table on x86-32.
This will at least make the "Faking node ..." message not print confusing
information anymore.
