Yes, without this patch and building into another dir with O=, kvmconfig
has more problems:

$ make O=/tmp/kernel kvmconfig
Using /tmp/kernel/.config as base
Merging arch/x86/configs/kvm_guest.config
sed: can't read arch/x86/configs/kvm_guest.config: No such file or directory
cat: arch/x86/configs/kvm_guest.config: No such file or directory
#
# merged configuration written to /tmp/kernel/.config (needs make)
#
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/conf.o
  HOSTCC  scripts/kconfig/zconf.tab.o
  HOSTLD  scripts/kconfig/conf
scripts/kconfig/conf --oldconfig Kconfig
#
# configuration written to .config

So, yes, we want it:
