Disable the usage of fulltext searches in the last union branch.
This is a temporary 5.x limitation because of the way the fulltext
search functions are handled by the optimizer.
This is manifestation of the more general problems of "taking away"
parts of a SELECT statement post-fix_fields(). This is generally not
doable since various flags are collected in various places (e.g.
SELECT_LEX) that carry information about the presence of certain
expressions or constructs in the parts of the query.
When part of the query is taken away it's not clear how to "divide"
the meaning of these accumulated flags and what to carry over to the
recipient query (SELECT_LEX).
