I think mp3lame doesn't support x86
Can you check that x86_64-linux-android works?
I think most modern hardware and emulators should be x86_64 anyway

[rosejober]

x86_64-linux-android

x86_64-linux-android is supported

[DoumanAsh]

Ok, so I think it is only problem with i686-linux-android
I do not really have solution right now because I'm not familiar with underlying mp3lame library so I cannot really answer it is supported or just problem with build system

I saw an article that describes the compilation of i686-linux-android, so lame should be supported for i686-linux-android compilation. Reference: https://blog.csdn.net/byhook/article/details/83926620

[DoumanAsh]

If you have suggestion how to make it work feel free to make PR
There is no much of explanation on whether there is need to modify build system to accommodate i686
And I cannot read chinese too

From log you can see that configure detected some weird CPU target:

error: unknown target CPU 'cyclone'

I'm not sure where it is coming from because you're compiling i686-linux-android

P.s. do you perform any customization of environment? mp3lame should be able to detect NDK toolchain automatically
