Make kvm configure script and Makefile work again after things have been

kvm-enabled qemu.
Also, guard against infinite recursion in case of 'cd' commands failing.

Also
for me running ./configure --kerneldir=/path/to/kernel at top dir works.
(/path/to/kernel should be absolute though, otherwise kernel include path
is incorrect).
Ah, I didn't realise kvm/cofigure is obsolete.

Here's a draft set of patches for MSI-X support in the guest. It still
needs to be tested properly, and performance impact measured, but I
thought I'd share it here in the hope of getting some very early
feedback/flames.
Michael S. Tsirkin (8):
virtio: add request_vqs
This adds 2 new optional virtio operations: request_vqs/free_vqs. They will be
used for MSI support, because MSI needs to know the total number of vectors
upfront.

This implements optional MSI-X support in virtio_pci.
MSI-X is used whenever the host supports at least 2 MSI-X
vectors: 1 for configuration changes and 1 for virtqueues.
Per-virtqueue vectors are allocated if enough vectors
available.

Sheng, Marcelo,
I've been reading code in qemu/hw/device-assignment.c, and
I have a couple of questions about msi-x implementation:
1. What is the reason that msix_table_page is allocated
with mmap and not with e.g. malloc?
2. msix_table_page has the guest view of the msix table for the device.
