    collect2: Fix missing cleanups.
    
    The code that checks to see if objects have LTO content via
    simple-object was not releasing resources, fixed thus.
    
    Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
    
    gcc/ChangeLog:
    
            * collect2.c (is_lto_object_file): Release simple-object
            resources, close files.
    
    (cherry picked from commit 43ae43f654749d291d871ca6ef7c96ea16580fad)
