Hello, I have noticed there exists a systemd-stub for aarch64, the file is located at `/usr/lib/systemd/boot/efi/linuxaa64.efi.stub`.
The manpage instructs users to use `objcopy` to build the unified kernel from the stub. However when I use objcopy I get the following error: ``` objcopy: /usr/lib/systemd/boot/efi/linuxaa64.efi.stub: file format not recognized ``` I also noticed the GNU binutils bug tracker indicates that PE executables on ARM are not yet supported for objcopy [0]. How do systemd developers build the unified kernel on aarch64? Is there an alternative toolchain used? [0]: https://sourceware.org/bugzilla/show_bug.cgi?id=26206 -- Zameer Manji
