    Add support for the AMD GCN GPU architecture.  This is primarily intended for
    use with OpenMP and OpenACC offloading.  It can also be used for stand-alone
    programs, but this is intended mostly for testing the compiler and is not
    expected to be useful in general.
    The GPU architecture is highly parallel, and therefore Newlib must be
    configured to use dynamic re-entrancy, and thread-safe malloc.
    The only I/O available is a via a shared-memory interface provided by libgomp
    and the gcn-run tool included with GCC.  At this time this is limited to
    stdout, argc/argv, and the return code.
