util/qemu: Add `qemu` make target
Add some mechanics to automatically have a `qemu` make target for supported configurations. So with a QEMU target selected in Kconfig, one would ideally only have to run `make qemu` to test things.
There are some notable variables that can be set or adapted in `Makefile.inc` files, the make command line or the environment.
Primarily for `Makefile.inc` use: QEMU-y the QEMU executable QEMU_CFG-y a QEMU config that sets the available default devices, used to run more comprehensive tests by default, e.g. many more PCI devices
For general use: QEMU_ARGS additional command line arguments (default: -serial stdio) QEMU_EXTRA_CFGS additional config files that can add devices
QEMU_CFG_ARGS gathers config file related arguments, can be used to override a default config (QEMU_CFG-y)
Examples:
$ # Run coreboot's default config with additional command line args $ make qemu QEMU_ARGS="-cdrom site-local/grml64-small_2018.12.iso"
$ # Force QEMU's built-in config $ make qemu QEMU_CFG_ARGS=
