[R-SIG-Win] Install multiple versions of Rtools

[Gábor Csárdi]

THanks!

Is it possible to make it work for both architectures? So that some R
utils like `R CMD check` automatically find both, in the same run,
like on the CRAN windows machines? There is a BINPREF64 env var as
well, but seemingly that is not picked up, and BINPREF is used for
both 32bit and 64bit.

I only way I could make it work was editing the Makeconf files, or at
least the one for 64bit, and set BINPREF there.
