    <sys/cdefs.h>: Copy attributes for strong/weak references.
    
    GCC 9 and later take issue with mismatched attributes between aliased
    functions. At the same time, the 'copy' attribute was added to copy
    the attributes for these cases.
    
    Change __{strong,weak}_reference() to use it. Fixes GCC 12.5's
    -Wmissing-attribute warnings.
    
    This is based on a patch by Scott Parlane <scott at parlanenz.com>, which
    was based on the change made in linux for the same issue.
