# The test suite fails if there are no OpenCL platforms available, and
# even if there is one (which requires the presence of both an OpenCL
# runtime *and* hardware supported by it - simply emerging any runtime
# is not enough) the vast majority of tests end up skipped because by
# default the portage user hasn't got sufficient privileges to talk
# to the GPU.
