[Rd] Cross-compilation

[Ramon Diaz-Uriarte]

Dear Tom,

It has worked for me out-of-the box in at least two times, one a while ago 
with R-2.2-something and recently with R-2.4.0. In both cases, I was running 
Debian (with a mix of testing and unstable) on x86. I never had to do 
anything, just run the script and at least in one case I did crosscompile a 
package with C++.
