[PATCH] Don't set $LIB if we're not targetting windows.

[Filipe Cabecinhas]

I may be misunderstanding, but:
It seems to me that, most likely, you don't want INCLUDE, since you want to
be sure of all the headers you include (and tests depend on a minimum set
of headers).

But you want LIB (on Windows targetting Windows) since that's where you can
find kernel32.dll and others.

LLVM tests only run on the host, so we don't have the “problem” of Windows
targetting some other platform. Because of that, we can simply forward LIB.
