This patch contains the configuration adjustments needed to enable the GCN
back-end.
The new configure check for dlopen is required to allow building the new
gcn-run tool. This tool uses libdl to load the HSA runtime libraries, which
are required to run programs on the GPU. The tool is disabled if libdl is not
available.
