Don't save x86_64-specific msrs if our kernel does not support them.
Code is already in qemu-kvm.git, but the test function is slightly different.
It follows what the test for msr_start does.
Repeat after me: "I will not use --target-list when submitting qemu
patches. I will not use --target-list when submitting qemu patches."
Fedora enables ccache by default. After one build, all future builds
are extremely fast in most cases. It's really not that bad :-)

This function is unused for qemu-system-i386.
