This is now present in the master branch.

You can build an EFI .iso in what is hopefully the most intuitive way:

   make bin-x86_64-efi/ipxe.iso

The build syntax doesn't provide a way to express multi-platform .iso 
images, but you can build them in two stages using e.g.:

   make bin/ipxe.lkrn bin-x86_64-efi/ipxe.efi
   ./util/genfsimg -o combined.iso bin/ipxe.lkrn bin-x86_64-efi/ipxe.efi

It will correctly handle multiple CPU architectures, so you build a 
single .iso that works on x86 BIOS, i386 UEFI, x86_64 UEFI, arm64 UEFI, etc.

This is a known issue introduced just a few days ago by commit 

I'm looking into a fix now.
