scriplet issues installing deps in f23 mock

[Cole Robinson]

I'm hitting scriplet errors when trying to build f23 qemu in mock on an up to
date f23 host. Example:

$ mock --root fedora-23-x86_64 --init
...
$ mock --root fedora-23-x86_64 --rebuild qemu-2.4.0-4.fc23.src.rpm
...

With many cascading failures after that.

However if I invoke mock and request installing all the deps manually,
everything works:

$ mock --root fedora-23-x86_64 --init
...
$ mock --root fedora-23-x86_64 --install SDL2-devel zlib-devel which chrpath

Anyone know what the issue is, or where to go from here?
