[PATCH 4/4] sim: Suppress non-literal printf warning

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

Clang generates a warning if the format parameter of a printf-like function
is not a literal.  However, on hw_vabort, it's unavoidable to use non-
literal as a format string (unless we make huge redesign).

We have "include/diagnostics.h" to suppress certain warnings only when
necessary.  Because DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL can suppress
warnings when the format parameter of a printf-like function is not a
literal, this commit adds this (only where necessary) to suppress this
error with "-Werror", the default configuration.

sim/ChangeLog:

	* common/sim-hw.c (hw_vabort): Suppress non-literal printf warning
	by using DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL.
