Found the problem, it seems I needed -cpu cortex-a57, it now drops me to the
shell.

But when I try to run my hello world I get a rather vague

Shell> fs0:hello.efi
Command Error Status: Not Found

I am 80% sure it's the linkerscript, as binutils is able to read and understand
the format as produced by clang+lld fine.

> file hello.efi
hello.efi: PE32+ executable (EFI application) (stripped to external PDB), for
MS Windows

> objdump -h hello.efi
hello.efi:     file format pei-littleaarch64

But afraid I don't know enough about EFI to debug the script. Is there a tool I
can use to validate the binary or figure out what that error means?
