If anyone is still interested in this, I've just built cgminer 4.10.0 for the Bitmain Antminer S3.

- Based on the latest cgminer 4.10.0 from git (changelog: https://raw.githubusercontent.com/ckolivas/cgminer/master/NEWS )
- Statically linked with the latest libcurl 7.54
- Built with gcc 5.3.0

Hashes just fine on my unit so far.
