Fails to build on i386

Hi,

I've uploaded the current git head of ipfixcol2 to debian and it fails to build on i386:

Hello,

thank you for the report. Seems like all of the reasons it's failing should be easy enough fixes. I will look into it as soon as I have some spare time and should hopefully be able to release a fixed version shortly after.

Have a nice day,
Michal
