Right now, it does do that with the sse2 extensions by putting them in
/usr/lib/sse2. I believe if sse2 is supported, the library loader
automatically puts /usr/lib/sse2 at the top of the path, so even if the
base atlas libs are also installed in /usr/lib, it picks the right ones.
However, when I last checked, this isn't necessarily the case for the
other subarch-specific extensions, such as sse and 3dnow. For those
ones, I also created subdirectories in /usr/lib, but I had to create
custom paths in /etc/ld.so.conf.d. It would be nice if all of these were
supported, but the other ones are a bit dated and less common now
anyway, so it probably doesn't matter too much.
