Right, but I believe it's two different (but related) matters:

 * On one hand, Mischa's approach is good to specify starting from
   which gcc version this or that architecture or architecture variant
   was supported. It allows to encode the "theory".

 * On the other hand, additional 'depends on' can be added
   exceptionally to prevent certain gcc versions from being selected,
   when they are supposed to work in theory, but in practice do not
   work due to bugs (that are likely to be fixed in the next point
   release).
