If not, kvm="yes" should be restricted to platforms with kvm support.
Otherwise, QEMU builds will fail very early:

but KVM depends on it when the IO thread is disabled.
Of course, users of those non-kvm platforms can set --disable-kvm,
but I don't think that is the correct solution.
Even with kvm disabled, builds still fail for non-kvm systems:

That indicates symlink emulation under Windows does not support
directories. Can you confirm this (check what
<builddir>/linux-headers/asm became)? Then we would have to link all
files in the arch header dir individually.

Even when cross compiling for w32 (on a linux host), kvmclock.c
does not compile:
$ LANG=C make CFLAGS=-g
CC i386-softmmu/kvmclock.o

Is kvmclock.c really needed for non-kvm platforms? Or does it simply need
a obj-i386-$(CONFIG_KVM) in Makefile.target?
