    Fix size of external_reloc for pe-aarch64
    
    This patch series finishes off the work by Jedidiah Thompson, and adds
    support for creating aarch64 PE images.
    
    This should be essentially complete: I've used this to create a "hello
    world" Windows program in asm, and (with GCC patches) a UEFI program in
    C. I think the only things missing are the .secidx relocation, which is
    needed for PDBs, and the SEH pseudos used for C++ exceptions.
    
    This first patch fixes the size of RELSZ; I'm not sure why it was 14 in
    the first place. This is the size of the "Base Relocation Block" in
    https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, and
    AFAIK should be 10 for everything.
