You will have installed the x86 version of the zlib1g-dev libraries.
Unfortunately headers are not uniform across all architectures.

If you want to ensure you have all the appropriate headers for cross
compiling QEMU do:

  apt-get build-dep -a arm64 qemu

But you may well run into problems if the distribution isn't fully
multi-arch clean. This is one of the reasons we use docker to isolate
our various cross build environments:

  make docker-test-build@debian-arm64-cross J=9 TARGET_LIST=aarch64-softmmu
