Compile nethack as a 64-bit binary

[gurrhack]

Google Play now requires 64-bit architecture support for native code. No new versions can be published on Google Play until this is solved.

It compiles fine but it's way too unstable for release.

请问如何编译arm64-v8a库
我使用的是android-ndk-r19c
我把里的ABI换为arm64-v8a，编译会提示不支持--fix-cortex-a8，去掉-Wl,--fix-cortex-a8后，运行起来，选择完阵营，就会直接退出游戏

How to compile the arm64-v8a library?
I use android-ndk-r19c.
I change the ABI to arm64-v8a in Makefile.src. When compiling, you will be prompted that "-- fix-cortex-a8 is not supported". After removing -Wl,--fix-cortex-a8. compilation can pass. After start game, when you choose your align, it will directly exit the game.
