commit 6e826c471b7f0431391a4e9f9484f6ea2833774a
Author: Richard Levitte <levitte at openssl.org>
Date:   Mon Jan 28 14:53:19 2019 +0100

    Android build: use ANDROID_NDK_HOME rather than ANDROID_NDK
    
    It apepars that ANDROID_NDK_HOME is the recommended standard
    environment variable for the NDK.
    
    We retain ANDROID_NDK as a fallback.
    
    Fixes #8101
