I checked if an external gnu-efi can be used but it's hard coded in
build-gnu-efi.sh.

The gnu-efi build start in mk/efi.mk line 51 by calling:
$(topdir)/efi/check-gnu-efi.sh $(EFI_SUBARCH) $(objdir)

Where:
topdir = output/build/syslinux-6.03
EFI_SUBARCH = ia32
objdir = output/build/syslinux-6.03/efi32 (build output directory)

The script check-gnu-efi.sh test if gnu-efi needs to be build.
If yes, it call build-gnu-efi.sh

The path to gnu-efi is hard coded by EFIDIR:
EFIDIR="$(readlink -f "$objdir/../gnu-efi/gnu-efi-3.0")"

I tried to comment this line and define EFIDIR=$(GNU_EFI_DIR) in
SYSLINUX_BUILD_CMDS.
But there are some build issues to be investigated.

But clearly, external gnu-efi is not supported anymore...

Indeed, I forgot to remove the "select", thanks.
