Describe the issue

This issue is comming while building onnxruntime wheel in termux. I use termux to build the wheel because it compiles the wheel with libandroid-support.so, etc. And to use onnxruntime within termux

While i can successfully generate the wheel by installing TermuxAarch inside termux. But unable to generate in termux.

Is there any way to fix.

So, what is the solution? @ranjitsingha do you have any success? I'm facing the same problem and don't understand why mlas is not compiling with neon functions on arm64-armv8 host.

@hariharans29 hello, I'm sorry for the offhand ping, but could you help with compiling onnxruntime-training under termux for armv8, or do you know someone who could help?
