databases/mysql56-client build failure on 9.2-STABLE i386

[Greg Rivers]

The recent update from mysql56-client-5.6.15 to mysql56-client-5.6.16 
fails to build on 9.2-STABLE i386.  It builds fine on amd64 (both 
9.2-STABLE and 10.0-STABLE).

Here's the error:

Is this a simple matter to fix, or should I open a PR?
