    rs6000: fix xcoff section encoding
    
    The encoding needs to be applied if the decl is not an alias: both a NULL
    summary *OR* the decl alias flag is false.  This patch updates the
    earlier fix to continue with the encoding selection if the summary is
    NULL.
    
    gcc/ChangeLog:
            * config/rs6000/rs6000.c (rs6000_xcoff_encode_section_info):
            Proceed if no symbol summary or the symbol alias flag is false.
