stdalign: relax _Alignof and tighten _Alignas test * m4/stdalign.m4 (gl_STDALIGN_H): Relax the _Alignof test, as it was too strict: alignof must divide offsetof, but it need not equal offsetof. Inspired by Joseph S. Myers's comment <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52023#c10>. Conversely, tighten the _Alignas test a bit, as the resulting alignment must be exactly 8.
