make buildworld fails with 8.2-RELEASE amd64 building STABLE

[Michael L. Squires]

"make buildworld" fails when trying to "make buildworld" (no options) 
with 8.2-RELEASE with 8.2-STABLE sources as of 2/6/2012 updated at 9:15 AM 
from ftp.freebsd.org.

The compile fails in the same spot every time; this is not a random 
failure.  I have seen some evidence, however, that there may be hardware 
problems.

The other hardware problem was a Broadcom GigE watchdog timeout and reset.

Hardware is a Tyan S2885 (dual dual-core Opteron) which has been running 
Windows XP SP3 for some time without problems, for what that's worth.

A Google search turns up nothing obviously related.
