configure: Move check for __x86_64__.

Move AC_CHECK_DECL(__x86_64__) before AC_MSG_CHECKING([for native-code
support]) so that the former's progress note does not arrive in the
middle of the latter's, like this:

checking for native-code support... checking whether __x86_64__ is declared... no
yes, for i386
