r200086 fixed Anton's first testcase but then he found another one.  See

Compilation failure with -mstrict-align on ppc64

The original testcase isn't failing, but this test fails to compile with
-mstrict-align:

/tmp/testcase.c: In function 'testcase':
/tmp/testcase.c:12:2: error: output number 0 not directly addressable
  asm volatile("# %0": "+m" (b->zot));
  ^

and passes without -mstrict-align.
