configure: Fix alignment tests when cross compiling

Browse Source 
When inserting custom code to AC_CHECK_ALIGNOF, make sure to not replace
the default includes, but instead append to them.

This fixes ALIGNOF_GUINT32 and ALIGNOF_GUINT64 that were both 0 when cross
compiling. The third 'unsigned long' test wasn't affected because the
AC_CHECK_ALIGNOF call didn't specify the optional 2nd parameter.
