Koop Mast 1e36af0daa Add pocl.
Portable OpenCL aims to be an efficient open source (MIT-licensed)
implementation of the OpenCL 1.2 standard. pocl uses Clang as an
OpenCL C frontend and LLVM for the kernel compiler implementation,
and as a portability layer. Thus, if your desired target has an LLVM
backend, it should be able to get OpenCL support easily by using pocl.

Deadlocks (freezes) on FreeBSD:
OpenCL applications using pocl on FreeBSD must be compiled with
options CFLAGS+=-pthread or CXXFLAGS+=-pthread, otherwise someone risk
that a library may not initialize the threading on BSD independently,
even if an ICD loader is used.
