would be cleaner imo to write:

#if defined(__mips__)
# if _MIPS_SIM == _ABIO32
    const char kArch[] = "mips";
# elif _MIPS_SIM == _ABI64
    const char kArch[] = "mips64";
# endif
#else

Done.

     const char kArch[] = "mips";
+#elif defined(__mips__) && _MIPS_SIM == _ABI64
+    const char kArch[] = "mips64";
 #else
 #error "This code has not been ported to your platform yet"
 #endif

     LogAppend(" ");
     LogAppend(n_cpus);
