Windows: run "git config --global core.autocrlf false" before cloning the repo

On my windows box, I experienced the following loop:

GROOB:~/work $ git clone git@github.com:ghc/ghc.git

You have an old time package in your GHC tree!

Please remove it (e.g. "rm -r libraries/time"), and then run
"./sync-all get" to get the new repository.

Turns out the problem is solved by deleting the repo, running:

git config --global core.autocrlf false

and checking out the repo again.

Thanks for the patch; I've done something similar, which automatically sets the setting and resets the repo when cloning if the repository has autocrlf set to true.
