If i remember correct if you are using kernel 5.7+ it is not possible anymore to easily build binder and ashmem as the some things have been removed from those kernels in mind of security.
The fix is to revert patch your kernel / those kernel things or just compile a kernel with ashmem and binder integrated.

You could try to follow my guide how to do this for yourself: (or download my pre-compiled kernel - without any warranty that it will work for you or any other warranties...) https://github.com/anbox/anbox-modules/issues/75#issuecomment-794079944
