[PULL 31/40] configure: stop user enabling plugins on Windows for now

[Alex Bennée]

There are some patches on the list that enable plugins on Windows but
they still need some changes to be ready:

In the meantime lets stop the user from being able to configure the
support so they don't get confused by the weird linker error messages
later.
