configure.ac: require >= gcc-4.5 for ARM iwMMXt

We're using a patched gcc-4.5, and having to modify configure.ac and
autoreconf between changes is annoying. And besides, 4.5, 4.6, and 4.7's
iwMMXt intrinsic support is equally broken, and we test a known broken
intrinsic in the configure test program, so the version check is rather
meaningless.
