Subject: pocl 0.8 (new formula)

Open source OpenCL 1.2 compatible driver, which allows people to link
their program against alternative OpenCL implementation on OSX (e.g.
Apple i5 CPU driver is quite buggy). Added patch to fix one hard coded
tool call and upstreamed patch to pocl trunk.

Closes #23826.
