Re testing GNUC,

I'm not sure the macro means "targeting Linux", and it seems totally
legitimate that a C compiler which doesn't implement any GNU extensions
would not define that macro. Musl is quite a likely choice for a non-gnu
compiler that wants to compile code to run against the Linux kernel.
