cygwin don't assume that windriver is installed

[ghost]

i'm too tired to look into making this check for the existence of the windriver installation and download the compiler like it does on linux if it's not there.
at the very least, the readme should mention that windriver is expected to be installed if running on ms windows.

When I was writing the scripts for Windows, I had assumed that people would have WindRiver installed. WindRiver comes packaged with a number of essential unix commands, so I decided to use those instead of figuring out how to get people to install them on their own. Since all I'm using are the linux commands and the compiler, they're not affected by the license expiring.

I could probably just as easily use gccdist (though that would require replacing workbench-3.0/ with workbench-2.5). The problem is that I'm not sure Cygwin and Git bash will have wget installed... which is the whole reason I'm using WindRiver unix commands.

I added a warning for now. Someone will have to verify that it works even with WindRiver installed - I have a nagging suspicion that it will fail because this year's WindRiver workbench is version 3.3, not 3.0

I can fix this if there's a demand for it, but I think most people would be fine with using MSYSgit on Windows instead of Cygwin.
