[Qemu-devel] [PATCH v2 1/2] Makefile: generate header file with the list of devices enabled

[Julio Montes <julio.montes@intel.com>]

v2: generate config-devices.h which contains the list of devices enabled

---
config-devices.h is an auto-generated header file that will use
config-devices.mak to define the list of devices enabled.
Configs that are set to 'n' are ignored.
