Pause is not good. It doesn't scale with system speed, it doesn't parallelize, who looks at build logs interactively anyway, except to get annoyed by the fact that it's still not done yet? This whole issue is getting more and more abstruse, ever since it was decided that the version should contain the git string, but at the same time autoconf should not rerun upon each version string change. In the medium to long run, Autoconf should be changed to not depend at autoconf run time upon a volatile version string. For example, AC_VERSION_STRING_FILE([.version]) could have semantics so that .version is read each time configure is run. That would mean that the configure script itself doesn't contain the version string (if this macro is used), but I think that is an acceptable compromise. (Automake could let the .version file be a config.status dependency automatically, of course.) I suppose then people will be upset that configure is rerun upon each version string change. I don't know how to prevent that, though. But at least with --config-cache it shouldn't take all that long. That being said, I don't care much whether your patch is put in place as an intermediate measure. BTW, why are you removing autom4te.cache? Working around some bug?
