[PATCH] rearrangement in toplevel configure.in

[Nathanael Nerode]

This is a small rearrangment in the top level configure.in; it pulls
the definition of is_cross_compiler up higher so that one more thing
can use it.

A large portion of this file will be carried over to the autoconfiscated
version, so I prefer to do some of the necessary rearrangement work
first.  (So that the individual steps are more obvious.)

Oh yes, tested on i686-pc-linux-gnu.
