[Wine] Bootstrapping mingw GCC with wine on linux

[rubenvb]

Is it possible to bootstrap GCC+binutils on a linux machine using WINE?

MSYS is horribly slow, and a VM with linux is no more than twenty times faster in the build process. The only thing a linux box can't do, is a "make profiledbootstrap", which squeezes an additional 10-15% out of the final binaries.

Thanks
