Re: [Qemu-devel] [PATCH v5 07/13] libqtest: Inline qtest_query_target_endianness()

There was only one caller; it's easier to inline things.

What's the benefit of this change? Having a separate function ease code 
reading. You might add the 'inline' qualifier but the compiler is smart 
enough to inline it.

Instead of this change I'd inline it and remove the return value, having 
a void function initializing s->big_endian. Matter of taste I think :)
