trivial patch: echo -e in ./configure

The following one-liner eliminates an annoying -e output during ./configure run if your /bin/sh is not bash or ksh:

$ ./configure
...
IO thread         no
Install blobs     yes
-e KVM support       yes         <===
KVM trace support no
fdt support       no
preadv support    no
$ _

(I dunno if it's qemu or kvm thing)
Thanks!
