Error when compiling for Android 11

[lishaocheng]

Compiling the Android 11 Linux kernel for imx8mp_evp sends an error, what could be that part of the reason?

The following are the compilation steps and error messages。

Hello lishaocheng

Is probably that you have another linux BSP or android compilated in your computer? the issue is weird I never seen before it said

Internal error. Please report to android-llvm@google.com.

So I suggest to send the log to that address is problem of your PC and android.

Regards
