[GOLD] alignment test

Browse Source 
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.
