gcc (both in the sense of compiler and driver proper) doesn't try to
figure out if it is a cross-compiler or not. It's a compile-time
parameter that determines how the compiler (the one that's being built)
should behave when it is executed. In this sense it's only important for
the Makefiles to know or figure out whether or not the compiler (the one
that's being built) is to be a cross-compiler or not. A running compiler
*knows* if it's a cross-compiler or not, because it was told so during
compilation (of said compiler).
