Cross-building Windows binaries using the mingw toolchain

[Florian Weimer]

I noticed that cross-building Windows binaries is currently not 
supported.  It seems that Hotspot in particular assumes that the host 
and target operating systems are the same (for examples, Linux-to-Linux 
cross builds are support).  Assuming I can get it to work within the 
current build system, would you be interested in integrating patches and 
carry them forward?

Cross-build support would make it easier for GNU/Linux developers to 
work on features that should have parity on Windows, but lack shared 
native sources (e.g. networking-related features).
