I don’t think this belong in this section to begin with. This section is about
CPU specifications. The type of wchar_t is at best a factor of the OS and CPU
together, and correctly belongs with the other wchar_t stuff below.

I assume that this should be defined for Android.

And the WCHAR_T_IS_UNSIGNED=0 definition in the MIPS group that follows is
almost certainly unnecessary.

Done
I have no idea; I've done it as !IOS to preserve behavior since I don't want to
accidentally break a platform I'm not familiar with.
Left a drive-by on https://chromiumcodereview.appspot.com/10448043/ but for now
I'm moving it as-is to preserve since I don't actually know or have any way to
test.
