    sim/erc32: Add ATTRIBUTE_PRINTF
    
    Clang generates a warning if the format string of a printf-like function is
    not a literal ("-Wformat-nonliteral").  On the default configuration, it
    causes a build failure (unless "--disable-werror" is specified).
    
    To avoid warnings on the printf-like wrapper, it requires proper
    __attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.
    
    This commit adds ATTRIBUTE_PRINTF to the printf-like functions.
