[GOLD] alignment test

[Alan Modra]

PowerPC gcc aligns char arrays to a word which results in the test
failing since it expects a char alignment for *_item4 variables.  As
the test already uses gcc attributes to assign variables to sections,
we may as well use an attribute to align too.

OK?

	* testsuite/plugin_layout_with_alignment.c: Explicitly align all
	variables.
