As far as having a temple rebuilt before this takes place, I wouldn't bet on that happening. The Bible simply states that he (The AC) enters the holy place. That would be the temple mount itself. As far as putting a stop to the sacrifices, read this bit of news.
The present-day Sanhedrin Court decided Tuesday to purchase a herd of sheep for ritual sacrifice at the site of the Temple on the eve of Passover, conditions on the Temple Mount permitting.
The modern Sanhedrin was established several years ago and is headed by Rabbi Adin Steinsaltz. It claims to be renewing the ancient Jewish high court, which existed until roughly 1600 years ago, and meets once a week.
Professor Hillel Weiss, a member of the Sanhedrin, told Haaretz on Tuesday that the action, even if merely symbolic, is designed to demonstrate in a way that is obvious to all that the expectation of Temple rituals will resume is real, and not just talk.

See, no temple needed for sacrifices. As an added bonus the resuming of any sacrifice near or around the temple mount will surely cause some problems. Talk about adding gas to a blazing file.
