accidentally I was able to reproduce it. So it seems that syslinux
depends on compiler supporting 32bit+64bit mix
and it has probes to enquire the compiler for supporting the above.
Now if you have standard install of ubuntu you
do not have gcc-multilib installed and hence the problem.

So, I would say the fix is to install gcc-multilib package on
debian-like systems and something similar for other distros

sudo apt-get install gcc-multilib

and then clean build syslinux-native should get you going
