I saw this too when updating systems across the compiler update.  As 
near as I can tell, some part of the build is not using the new 
"core2"-aware compiler built as part of the toolchain and is using the 
older, installed version instead.

Commenting out the CPUTYPE definition allowed my buildworlds to complete 
successfully.  After the resulting system was installed I was then able 
to restore CPUTYPE to "core2" and 'make buildworld' would succeed 
(presumably because the base system compiler now understands 
"-march=core2").

Hope this help...
