Well, recently I moved my development environment from Lubuntu 15.10 to 16.04 LTS. After installing XSDK and Petalinux 15.2 (yeah... I am still at 15.02 because I don't want my client to update to a new XSDK in the middle of the project and cause a number of problems...)
$ petalinux-build

Hmm... What a bummer!
After searching for a while, I found this topic in xilinx forum
Following the advice on the link, I executed
$ sudo apt-get install tofrodos iproute tftpd-hpa gawk gcc git-core make
net-tools libncurses5-dev zlib1g-dev libssl-dev flex bison lib32z1
lib32ncurses5 lib32bz2-1.0 lib32stdc++6 libselinux1

E: Unable to locate package lib32bz2-1.0
E: Couldn't find any package by glob 'lib32bz2-1.0'
E: Couldn't find any package by regex 'lib32bz2-1.0'
Hm... Looks like lib32bz2-1.0 is not present. Can it be renamed to something else?
Further searching using google yielded this link
The fix was easy.
sudo dpkg --add-architecture i386

Great! Petalinux started building.
