[Qemu-devel] [v2 05/71] Makefile: Clone kconfig git submodule in Makefile

[Ákos Kovács]

configure: Append CONFIG_DEVICES_FILE=config-all-devices.mak to the 
config-host.mak
Use this new variable to control the current device configuration place.

If the user wants to configure QEMU with Kconfig, replace
config-all-devices.mak to kconfig-devices.mak at config-host.mak to
use the new configuration.

Make defconfig target capable to restore the original behaviour.
