--target-list specifies the target architecture, which to
QEMU means the architecture the guest code runs. The
architecture of the host (the machine QEMU runs on) is
determined by what compiler you are building it with.
If you run configure on an x86 machine and do not tell it
"hey, you should build this with this cross compiler" then
configure will just use 'gcc' and you will get x86 binaries.

Typically you want to pass configure something like
but this will only work if your host has the complete
aarch64 cross-build environment set up, including the
toolchain, pkg-config and all the necessary dependent
