make sure configure fails if AC_CHECK_ALIGNOF cannot detect the alignment

When cross-compiling with gcc >= 4.5 AC_CHECK_ALIGNOF fails to detect the
correct alignment. Without a previous AC_CHECK_TYPE for the same type, the
alignment is silently set to '0'.
This makes sure that configure fails and reports the problem.
