It's straightforward to extend my patch to the __i386 case.  It's somewhat
less straightforward to add configure tests for all the *at functions
here.  But I only have access to 64-bit Linux at the moment, so I can't do
proper testing.  It makes sense for someone at Oracle to make more
extensive changes.  Feel free to do a friendly takeover of this change.
The total amount of work will end up smallest if JDK-8165620 actually gets
tackled.
