Thanks! Based on some IRC discussion I ended up with:
boot_targets "dhcp mmc0"
It successfully falls back to mmc0 if network boot fails (although it
takes a while and tries twice).

It first tries to interpret the downloaded file as a script, then
downloads it again and executes it as an EFI binary - I see two dhcp
invocations in bootcmd_dhcp; I suppose this is also the reason DHCP
has to fail twice before fallback to mmc0.
