[syslinux] Syslinux 6.03-pre7: EFI64 broken

[Gene Cumm]

Using both a disk load and netboot, the precompiled binaries of
Syslinux 6.03-pre7 for EFI64 appear broken.  Testing 6.03-pre6 on the
same system results in a successful boot.

This does not appear to affect the BIOS architecture and likely
affects EFI32 also.
