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.
