Я разобрался, как надо собирать ATLAS.
Вот предварительный benchmark.

Fortran BLAS:

> mm <- matrix(rnorm(10^6), ncol = 10^3)
> system.time(crossprod(mm))
[1] 1.572 0.004 1.580 0.000 0.000

ATLAS w/ SSE2:

> mm <- matrix(rnorm(10^6), ncol = 10^3)
> system.time(crossprod(mm))
[1] 0.344 0.020 0.369 0.000 0.000
