The general criteria for primary, secondary, and tertiary platforms are described on the page to which you linked.
The choice of level is decided by the GCC Steering Committee in consultation with the GCC Release Managers and the maintainers for the targets / platforms. AIX is an unusual platform that always has required extra effort from the GCC community. The reduction in participation and investment from IBM means that the GCC community cannot tie its functional status to the release criteria for GCC.
