    [testsuite] scanasm.exp: Fix target-selector handling in check-function-bodies
    
    {target { ! a } } does not work because the greedy regexp extracts
    "! a }" instead of "target { ! a }".
    
    This patch replaces it with a non-greedy regexp.

            * lib/scanasm.exp (check-function-bodies): Use non-greedy regexp
            when extracting the target selector.
