This change is related to new nanoMIPS platform in the sense that it supports a different set of "stat" system calls than any other target. nanoMIPS does not support structures stat and stat64 at all. Also, support for certain number of other system calls is dropped in nanoMIPS (those are most of the time obsoleted system calls). Without this patch, build for nanoMIPS would fail.
