Control: tags -1 + patch fyi, I upgraded the package here: https://launchpad.net/ubuntu/+source/pocl/0.13-0ubuntu2
As mentioned in #823528, you might want to introduce some new binary package, or rename the library package. I think some symbols were lost too in 0.13.
I haven't checked if the glibc-2.23 fix works this way with 2.22.
