I'm mostly OK with that. I'd say it technically violates the coding
style because of assigning a value to Str on definition, but I can't
convince myself to care about that for a macro.
However, it still needs to have the name indicate that it's a macro,
so SET_HII_STRING_IF_PCD_NOT_EMPTY.
Best Regards,
Leif
