[Qemu-devel] [PATCH] Set a useful default for kerneldir

[Andi Kleen <andi@firstfloor.org>]

When no explicit kerneldir is specified use the standard
/lib/modules/$(uname -r)/build
convention to find the kernel includes. This should work out of the box 
on a large number of distributions.

Also support separate objdirs.
