cmake,win32*.sh: Add OS=(ubuntu|suse) flag, for distro settings

Distributions such as SUSE and Ubuntu differ significantly in their mingw
environments. This adds an OS=(ubuntu|suse) flag, which can be used to
specify which environment is being used for the build. Unless set explicitly,
the scripts will try to automatically detect it.

Depending on the OS selected, various mingw configuration options (binaries,
library paths, etc.) as well as required packages are determined.

Due to these options being configured at runtime, corresponding cmake
files are generated on the fly.
