I tried the version at this page, with the same failure on EFI32 and EFI64 as with kernel.org versions.
BIOS (lpxelinux.0) still worked OK.

I tried this one too, which contains just EFI32 & BIOS. 
EFI32 fails in same was as x86_64 version.

No idea, I've triple checked I'm not doing something stupid when copying the files to tftp folders etc...  and I scripted it so can flit between versions easily - back to pre11 and booted ok....

If I can, I'll try on a physical EFI machine tomorrow (instead of VMWare WS).

Wouldn't the two versions I just tried need the patch adding ?? (As mentioned - I failed to figure out how to build from source...!)

Hope that helps at all,
Andrew
