    LD/testsuite: Add STB_GNU_UNIQUE cross-linker test
    
    Some targets are only really, or at least regularly, regression-tested
    in a crossed configuration.  Currently we only have native compiled test
    cases for the STB_GNU_UNIQUE feature in the linker test suite.  This is
    nice, covering run-time semantics even, but quite often not run at all.
    Consequently a regression may remain unnoticed for long.
    
    Add a simple test case then to provide basic linker coverage with no
    need for a compiler or a native toolchain.

    	* testsuite/ld-unique/unique.d: New test.
    	* testsuite/ld-unique/unique.exp: Run the new test.  Adjust
    	messages for compiled tests.
