Do we really need the separate .x11-buildlink directory?

I have been using modular X.org on a few machines. Today, I noticed 
(remembered) that --x-includes and --x-libraries was being set to my 
X11BASE but I didn't even use it.

So I set X11BASE to LOCALBASE. And then buildlinking broke, for example 
for graphics/mng the .buildlink and .x11-buildlink directories were 
different and lcms when into .buildlink and jpeg went into .x11-buildlink 
and the build failed because of no jpeg headers.

Simple fix. I just cut out the code that set 
buildlink_dir="${BUILDLINK_X11_DIR}".
