Well, I've broken the build while trying to fix #256. Works for me but not on travis or for you.

Probably fixed by reverting

fdfbfb3

otherwise the entire series will have to be reverted...

[kannaiah]

Although it is building 64 target, 32bit libs are required.
Looks like I didn't have 32 bit libs not installed properly.
After installing I was able to build

apt-get install gcc-multilib g++-multilib

But still had issues running will use previous working sha.
Thank you.

I've reverted the broken commit with 500a707, so closing this and hoping it will stay closed :-)

#256 was there to build a 32-bit version of the system-mode library, even on 64-bit systems, but I think it will require more cmake magic in order to detect if 32-bit build support is actually present first.
