Dont override libdir on Windows MSVC.

[MAJigsaw77]

Currently if someone wants to change the libdir, it'll override itself to obj/lib, whats funny is that from my testing, only Windows's MSVC has this issue currently.

This ended up not working but this code did the thing.

<section unless="static_link">
	<copyFile toolId="dll" name="${PROJECT_NAME}.lib" from="obj/lib" if="windows" />
</section>

When the libdir was removed from the toolchain, it also added files like .exp, .ilk and .pdb which arent needed.
