Compilation error about csom

[interstar]

Cool. Yeah. That works. (That change to 64bit architecture)..

Thanks.

@interstar this doesn't look like a CSOM dependency.
In CI we only install this: https://github.com/SOM-st/CSOM/blob/master/.travis.yml#L5
libc6-dev-i386 gcc-multilib

Looking at the error, it fails with the include of stdio.h, because some bits/libc-header-start.h header does not exist.
This is a dependency of stdio.h on your system and unrelated to CSOM.

An a Ubuntu system, I'd normally expect build-essential to provide all needed dependencies.
Though, you may need to specify the architecture explicitly. So, instead of make, rather ARCH=64bit make.

Instead of updating the readme, I decided to set the default architecture to 64bit #20

This might fix your issues. Not sure.
