Hmm, actually setting W32_CROSS won't to anything, I must have been
tired when I wrote that. :) The current behaviour is that if the
OS environmentvariable is set you use the value in it, if it isn't
OS will be set to `uname -s`. The OS variable is then used to select
the proper config/rules/ file.

And the ability to build on any system that has uname without any 
manual configuration done by the user must be kept. Also, configurable
things should not be hidden, rather they should be in Make.options
or similiar.
