Note: i fixed this (or actually worked around it) by removing my
system Qt 5.1 packages since only QtCreator was dependent on that. I'm
using ArchLinux btw. I wasn't expecting those system packages to be a
problem because they had a lower version. Apparently that is a
problem..

After that was removed the rest compiled just fine.
