You cannot chroot into different architecture. By chrooting, you are executing the binaries (from the chroot) on your architecture. Executing ARM binaries on x86 (and x86_64 in that matter) would lead to "Exec format error".
If you want to run binaries from different architecture you will need an Emulation, Qemu is a good candidate for this, but you will need to learn how to use it. This would involve creating RootFS and compiling a kernel for ARM, you will need a toolchain for compiling ARM binaries (and kernel) perhaps. One thing is for sure: Forget the chroot method, you cannot run binaries compiled for ARM on x86 (x86_64).
