yes, I can build it. I was using 'make bios' as an intermediate step,
but apparently it's not needed for installer.

As I mentioned, I don't have multilib, building pure 64-bit installer.

# cd syslinux-6.03
# ldd bios/extlinux/extlinux
    not a dynamic executable
# make bios clean
# make bios installer
# ldd bios/extlinux/extlinux
    linux-vdso.so.1 (0x00007fff53b6d000)
    libc.so.6 => /lib/libc.so.6 (0x00007f53e53fd000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f53e57a0000)
# file bios/extlinux/extlinux
bios/extlinux/extlinux: ELF 64-bit LSB executable, x86-64, version 1
(SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2,
for GNU/Linux 2.6.32, not stripped

problem solved :-)

Thanks for clarification,
