[Rd] Developmental version of Matrix package for R-1.9.0

Builds OK on OS X, except for

1. The static archives foo.a are not ranlibbed, so you have to do
that manually.

2. Cannot build Matrix.so because it uses flat namespaces and
has multiple definitions of some symbols.

I solved 2 by the usual hack, which is to add the -Xlinker -m flag
to the link by the gcc driver, but the preferred solutions would be
to use external in the code. Or, even better, to switch the Darwin
build to two-level namespaces.
