[Qemu-trivial] [PULL 06/16] docs/devel/build-system: Update an example

[Laurent Vivier]

From: Philippe Mathieu-Daudé <address@hidden>

The default-configs/ example added in 717171bd2025 is no
more accurate since fa212a2b8b60 (and various further other
commits).

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

 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

+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
