Subject: 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.
