docs/devel/build-system: Update an example 



The default-configs/ example added in 717171bd is no
more accurate since fa212a2b (and various further other
commits).

The Kconfig build system is now in place.
Use the aarch64-softmmu config as example.

- default-configs/*.mak



The files under default-configs/ control what emulated hardware is built

into each QEMU system and userspace emulator targets. They merely

contain a long list of config variable definitions. For example,

default-configs/x86_64-softmmu.mak has:



  include sound.mak

  include usb.mak

  CONFIG_QXL=$(CONFIG_SPICE)

  CONFIG_VGA_ISA=y

  CONFIG_VGA_CIRRUS=y

  CONFIG_VMWARE_VGA=y

  CONFIG_VIRTIO_VGA=y

into each QEMU system and userspace emulator targets. They merely contain

a list of config variable definitions like the machines that should be

included. For example, default-configs/aarch64-softmmu.mak has:



  include arm-softmmu.mak

  CONFIG_XLNX_ZYNQMP_ARM=y

  CONFIG_XLNX_VERSAL=y



These files rarely need changing unless new devices / hardware need to

be enabled for a particular system/userspace emulation target
