You need to do the globbing first.  In conditional expressions you get
single-word expansion that doesn't do globbing.

You'll need something like the following --- the (N) flag is needed if
you want the string to be empty if there's no match (unless you have the
NULL_GLOB option set, which isn't standard).

matches=(fubar(N/F))
[[ -z $matches ]]
