How to grant android.permission.RECORD_AUDIO permissions to android shell user?

I build some command line tool with android NDK and execute it in /data/local/tmp. Now it prompts me “requires android.permission.RECORD_AUDIO”. It's usually in AndroidManifest.xml for java application, but how to grant it to android shell user?

Source code like:

sp<AudioRecord> rec = new AudioRecord(AUDIO_SOURCE_MIC, 44100, AUDIO_FORMAT_PCM_16_BIT, AUDIO_CHANNEL_IN_MONO);

Logcat:
