dev-util/opencl-headers: new package
The first release of unified Khronos OpenCL headers, which unlike
old headers (which is what app-eselect/eselect-opencl installs)
work with all released OpenCL versions rather than having different
versions supported by files from different directories.
Note that in order to avoid file collisions with eselect-opencl this
package presently installs header files into
/usr/$(get_libdir)/OpenCL/vendors/opencl-icd-loader/include ,
which is why it needs multilib support and why it will likely not work
right when installed standalone (in contrast to being pulled in by
dev-libs/opencl-icd-loader).
