Sure. I would expect no breakage, because
1) I'm only modifying the cross-compilation guess part.
2) I'm checking the "configure" output from a cross compilation
$ ./configure --host=x86_64-pc-linux-gnu --build=x86_64-unknown-linux-gnu
against the one from a native compilation
$ ./configure --host=x86_64-pc-linux-gnu
to verify that each change is good.
