Bug#1014978: How about version 4.12.1?

[Al Ma]

I have the same request: please kindly consider upgrading.
For my purposes, I ask specifically for version 4.12.1 (which is NOT the most 
recent version of Z3) because that's the one currently requested by dafny in 
https://github.com/dafny-lang/dafny/wiki/INSTALL#linux-source .
