Calculate the optimal memory location for overlay plugins, and use plugin.lds for linking them. This gets rid of hand-adjusted archos.lds, making it easy to use overlay plugins on other lowmem targets. * Fix some duplicate and incorrect dependencies. * Change the way libs are filtered, so that a lib can be specified more than once. This allows to get rid of explicitly linking gcc-support.o, fixing empty plugins on some simulator platforms.
