I'm not sure downgrading is a good idea, it might impact your host in a negative way.
Are you using a virtual machine to build LFS? If so I would suggest using a host that is compatible. Ubuntu 12.04 and Debian 6 are compatible (as in: not having package that are too new), have a look here if you want/need a reference: Minimal Graphical Debian Host for LFS
/ LFS 7.1 on Ubuntu 12.04
Although you cannot rule out gcc 4.7.2 being the culprit, you might want to post a few more error lines (5 to 10 before the first make error line). Maybe there's another clue in there.
