[Rd] optimized BLAS

As a few of you will know, Dr Goto's BLAS is now available again
(http://www.tacc.utexas.edu/resources/software/software.php), but only for
academic use and only for Linux (at least in binary form, and source-code licenses are not yet available).

http://www.netlib.org/lapack pointed me to AMD's ACML
(http://www.amd.com/acml). This has a less restrictive licence, and seems
at least as fast as the Goto BLAS - it is also a full optimized LAPACK.

What does seem a bit confused is all the references to AMD64, when they also supply 32-bit non-SSE2 and even non-SSE versions (and there are no such versions of AMD64 to my knowledge). It runs on my Athlon XP systems, and even under Windows.

I've added comments in R-admin.texi and Windows support, in both R-patched and R-devel.
