Drop the deprecated unicore32 target
Target unicore32 was deprecated in commit 8e4ff4a8d2b, v5.2.0. See there for rationale. Cc: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20210503084034.3804963-3-armbru@redhat.com> Acked-by: Thomas Huth <thuth@redhat.com>
