You asked what else is needed.

Patches are welcome.

Debian already does what it needs:
 
http://sources.debian.net/src/syslinux/3:6.03%2Bdfsg-4/debian/patches/00
04-gnu-efi-git.patch/ 

As an additional example, Mageia solves it for its development 
environment:
 
http://svnweb.mageia.org/packages/cauldron/syslinux/current/SOURCES/sysl
inux-nogit.patch?view=markup&pathrev=600959 

If you are using Ubuntu 14.04 and you want to use Syslinux 6.03, then 
either:

_ use the Debian relevant packages related to Syslinux 6.03; or,
_ use the built-in binaries already included in the official upstream 
distribution archives from kernel.org.

Official upstream Syslinux will still be built with a specific commit 
of 
gnu-efi and using git.
