Add swig binary built against statically linked PCRE on a stock CentOS 6.5 with stock gcc and family

- CentOS 6.5 with gcc 4.4.7-4
- PCRE version 8.36
- SWIG version 3.0.2
- Tested this binary with our CI pipelines. All tests passed.

It passed our tests. Hope this PR passes the travis tests as well.
