Subject: [PATCH] build: disable -Wattributes warnings on aix

Disable the following compiler warning:

    warning: visibility attribute not supported in this
    configuration; ignored [-Wattributes]

This is gcc complaining about `__attribute((visibility("default"))`
in static library builds. Legitimate but harmless (and uninteresting)
and it drowns out more relevant warnings.
