    libgomp/plugin/plugin-gcn.c: Use -foffload-options= in err msg
    
    While -foffload=-<flag> works (never documented legacy feature),
    the documented way is to use -foffload-options=.
    
    libgomp/ChangeLog:
    
            * plugin/plugin-gcn.c (isa_matches_agent): Suggest -foffload-options.
    
    (cherry picked from commit 4a2061610726becfa5158e418c69800f5634b4c1)
