[syslinux] upgrade 6.04-pre1 to 6.04-pre4

[juerg oehler]

hi

i'm about to upgrade systems.

yesterday i got 
https://www.zytor.com/pub/syslinux/Testing/6.04/syslinux-6.04-pre3.tar.xz 
in order to upgrade 6.04-pre1 version.

i first was upgrading a usb-disk which was booting smootly with a simple 
configuration.

i changed the EFI installation in /EFI/BOOT:
efi64/efi/syslinux.efi (UEFI bootloader for EFI X64 (x86_64) firmware) → 
/EFI/BOOT/bootx64.efi
efi64/com32/elflink/ldlinux/ldlinux.e64 →> /EFI/BOOT/ldlinux.e64

i did not touch sysls64.cfg

after this action, the bootdisk was not recognized any more by uefi system.

i just replaced syslinux-6.04-pre4 bootx64.efi by the old version 
syslinux-6.04-pre1 and the bootdisk was detected and booted again.

size of pre1 version: 200992 B
size of pre4 version: 182728 B

have fun
