[Buildroot] [PATCH v2 1/1] rtl8821au: new package

[Christian Stewart]

Adding a kernel module based USB wifi driver. There is no official
version of this driver that works properly on ARM and with newer USB
WiFi cards. This driver version builds module 8821au and is based on a
kernel module release from ASUS with various fixes integrated in.

[Thomas, Yann:
  - Using the new kernel-module setup]

s/ENDAIN/ENDIAN/

Besides, since BR2_ENDIAN is an uppercase string, why not replacing
these 5 lines with (untested):

   RTL8821AU_CFLAGS_ENDIAN = -DCONFIG_$(call qstrip,$(BR2_ENDIAN))_ENDIAN
