Using gcc4 to compile qemu will generate broken code for its cpu emulation but should be fine if using kvm only.
This will allow users that have no access to gcc4 on their platforms to at least get kvm compiled and use it while preventing them to run a broken qemu if kvm is not available. This is not meant to be used in the long run when a solution to qemu's use of gcc-3.x for code generation is finally resolved upstream, which is why it is kept inside the KVM specific sections of the code only.
