This one looks a lot better to me.

[kvm-devel] [PATCH] [v5] Add cross compile top level configure script
This patch takes feedback from Anthony Liguouri.
- remove --cc option added in v4 of patch (keep old behavior)
- do not specify cc= everytime on the qemu configuration line, this
allows qemu to autodetect gcc 3.x
This simplifies the patch more. While preserving behavior.
