Dmitry Kozlyuk abc61614f8 eal: introduce portable format attribute
When using __attribute__((format(...)) on functions, GCC on Windows
assumes MS-specific format string by default, even if the underlying
stdio implementation is ANSI-compliant (either MS Unicersal CRT
or MinGW implementation). Wrap attribute into a macro that forces
GNU-specific format string when using GCC.

Use this new attribute for logging and panic messages in EAL
and for output strings in cmdline library.
