yeah, the patch changes libkvm and thus i reinstalled libkvm when i
tested it:

-rw-r--r-- 1 mingo mingo 23326 Dec 28 14:11 user/libkvm.a
-rwxr-xr-x 1 mingo mingo 3932505 Dec 28 14:11 qemu/i386-softmmu/qemu
-rwxr-xr-x 1 root root 23326 Dec 28 14:13 /usr/local/lib/libkvm.a

and rebuilt qemu with the new libkvm, but it still gave me this warning.
I'll do a full qemu rebuild, just to make sure it picked up the new
library ...
