I once tried to build ATLAS once and for all (for an old laptop where I was tired of waiting overnight for building Sage), and I eventually failed, but not before finding that there was a mismatch between what the spkg install script thinks the list of architectures is, and what the ATLAS makefile thinks the list of architectures is. So, it may be that you are telling Sage to build ATLAS for a Corei7, but then ATLAS actually hears that it should build for a different architecture.
I thought I had created a ticket for this, but now I can't find it. It takes a certain amount of work to get the list of architectures for ATLAS: if I recall correctly, there is a 'make' target which will create diagnostic/documentation programs, and running one of them will tell you the list of architectures, along with the corresponding flags to specify each one. It may be less work to just use the new ATLAS-3.10 spkg, as Volker suggests.
