I tried that too.  No joy.

I tried x86_64-darwin-apple and x86_64-osx-apple.  Configure didn't  
like either one.

checking build system type... Invalid configuration `x86_64-osx- 
apple': machine `x86_64-osx-apple' not recognized
configure: error: /bin/sh ./autoconf/config.sub x86_64-osx-apple failed

checking build system type... Invalid configuration `x86_64-darwin- 
apple': machine `x86_64-darwin-apple' not recognized
configure: error: /bin/sh ./autoconf/config.sub x86_64-darwin-apple  
failed

That's what I thought.

That makes two of us then.
