[PATCH] winegcc: Fix cross linking on multiarch platforms.

[Jacek Caban]

From: Andre Heider <a.heider(a)gmail.com>

If e.g. the 64bit libdir was set to /foo/lib/x86_64-linux-gnu/bar, winegcc
will now look for the 32bit libdir at /foo/lib/i386-linux-gnu/bar.

I simplified string copies a bit and fixed off-by-one mistake.
