[syslinux] EFI build problems

Previous points still standing, but now I tried cleaning out everything
by hand.  I don't know whether it matters, but building gnu-efi pollutes
its source directory (unlike syslinux itself) with the following files
at least (found by git status in the gnu-efi submodule):

gnu-efi-3.0/gnuefi/crt0-efi-ia32.o
gnu-efi-3.0/lib/libefi.a

After removing these and the bios, efi32 and efi64 subdirectories, the
build failed ending with the following messages:

Issuing another make after this gave the previous error again:
