[Bug c/46636] attribute aligned is documented as using bytes, uses addressable units instead.

A 32 bit wide character is not a byte, it is four bytes.

The documentation states:
 You can also specify the alignment of structure fields.  For example, to
 create a double-word aligned @code{int} pair, you could write:

 @smallexample
 struct foo @{ int x[2] __attribute__ ((aligned (8))); @};
 @end smallexample

If, on a 32-bit word-addressed target, this is aligned to 8 words
instead of two, that would be unexpected.
