I considered cross compiling it, but given my timeline, it wasn't too bad to start compiling 4.7.3 on this host, then leaving for the night.
4.7.3 was finished when I came in the next morning. (less that about 16 hours.)
On the other hand, building 4.8.2 with 4.7.3 on this old Ultra 10 has been grinding away now for more than 27 hours.. (But hey, at least it's compiling.
That's a huge improvement over building it with 3.4.6..)
