[PATCH 5/7] sim/m68hc11: Add ATTRIBUTE_PRINTF

[Tsukasa OI <research_trasio@irq.a4lg.com>]

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 a printf-like function.

sim/ChangeLog:

	* m68hc11/m68hc11_sim.c (sim_memory_error): Add ATTRIBUTE_PRINTF.
	* m68hc11/sim-main.h (sim_memory_error): Likewise.
