The default "make" will attempt to build the standard i386 BIOS targets, 
which won't work with the arm64 version of gcc.  You need to choose a 
suitable arm64 UEFI target, e.g.

   make bin-arm64-efi/8086100e.efi

Note that the "all-drivers" build (bin-arm64-efi/ipxe.efi) is 
non-functional at present, since we have no arm64 implementation of the 
port I/O primitives (inb()/outb() etc.).
