It is possible to return a pointer to a local variable when looking up the architecture name for the running system and no normalization is done on that value, i.e. we may end up returning the uts.machine local variable. While this doesn't happen on most arches, as normalization takes place, lets fix this by making that a static variable and optimize it a bit by not always running uname(), only the first time.
