It depends what you call "cross-compiling".
If you mean "compiling for an incompatible processor" then you're right,
it's not coross-compiling, but this is not always crystall-clear: are
PentiumIII-Xeon and 386SX compatible processors? (it further depends on the
order we list them).
If you mean "compiling for a machine which can execute any program running
on the local system, except for missing optional features", then you are
wrong and this is cross-compiling.

These are not gratuiitous: if you want native compilation, you just
./configure
If you
./configure --host=something
that is because you expect not to be compiling for the local system, so you
are prepared to be cross-compiling, and get what you requested.
