cross-compile for android

[erophey7]

Hi, I'm trying to build this driver for Android I already tried to assemble it as an out-of-tree module, and put it when compiling it in driver/net/wireless/realtek/this driver

In 1 case the following error appears:

Hi @erophey7

Let me merge some changes to the scripts and configuration which may help. Once that is done, I will let know and we can figure it out from there.
