Bug#760232: [viennacl] Build dependency on virtual libopencl1 with no default

[Graham Inggs]

Source: viennacl
Version: 1.5.2-1

Hi Maintainer

The viennacl source package has build-dependencies on 'opencl-headers,
libopencl1'.  Binary package libviennacl-dev has dependencies on the
same.
Libopencl1 is a virtual package and so should be preceded by a real package.
However, package ocl-icd-opencl-dev already depends on opencl-headers
and libopencl1, so it can replace both.  In addition, allowing the
opencl-dev alternate dependency will allow the package to be built
locally with any alternate OpenCL implementation.

The attached patch replaces the dependencies on 'opencl-headers,
libopencl1' with 'ocl-icd-opencl-dev | opencl-dev'.

Regards
Graham
