Please provide a more accurate version than this. In the rest of this
email i will therefore consider the latest glibc version, in sid, ie
2.38-11:

The bits directory is not omitted, it is provided in
/usr/include/aarch64-linux-gnu following the multiarch path convention.

I guess you are building gcc from source. For using the multiarch path
convention, you should configure it with --enable-multiarch.
