how to add "=lnnz11" to the list of linked libs

[jusongchen]

Can anyone tell exectly what I need to do to add "=lnnz11" to the list of linked libs? This is what it says on this project's README.md :

WARNING: If you have Oracle Instant Client 11.2, you'll need to add "=lnnz11" to the list of linked libs! Otherwise, you may encounter "undefined reference to `nzosSCSP_SetCertSelectionParams' " errors. Oracle Instant Client 12.1 does not need this.

Also, "=lnnz11" looks odd, should it be "-lnnz11"?

I am using Oracle Instance Client 11.2, and I got:

$ go build -a
