Hmm - why moving '-L' library path in before '-o' option?

I think the '-L' should be rather right before '-l' library
(i.e. part of LVMLIBS)
LVMLIBS += -L. -ldevmapper-event -lpthread -ldevmapper

or maybe even more complex (eventually partially placed in make.tmpl.in)

DEVMAPLIBS = -L. -ldevmapper
DEVMAPELIBS = -L. -ldevmapper-event -lpthread

LVMLIBS += $(DEVMAPELIBS) $(DEVMAPLIBS)

And actually - why the -L. is used ? We are already changing LDFLAGS in
make.tmpl to support separate build directory. Thus I think -L. should be
possibly avoided in this case ?
