How to find out if a given gcc is a cross compiler?

- Subject: How to find out if a given gcc is a cross compiler?
I'm looking a nice and simple way to find out if a given gcc command
actually specifies a cross compiler, or if I'm cross compiling when
using it, if you like. Does anyone know a simple way to find out? I
suppose I can compare the target type as output from -dumpmachine with
the current host type, but is there a single, reliable way of finding
that, and getting the value in the same format as the target? Or should
that be "build" machine instead of "host"? I never seem to learn which
is which, but the point remains: I'm not sure I know a good way to find it.
I'm usually building on a Linux system, but would very much prefer the
method to be as portable as possible.
