    [GOLD] alignment test
    
    PowerPC gcc aligns char arrays to a word which results in the test
    failing since it expects a char alignment.  As the test already uses
    gcc attributes to assign variables to sections, we may as well use an
    attribute to align too.
    
    	* testsuite/plugin_layout_with_alignment.c: Explicitly align all
    	variables.
