    icons: fix generated Symbolic-Inverted icons dependency.
    
    They need to be properly dependent on the image with the same name
    in the Symbolic icon theme. Until now we could only make them dependent
    on either nothing or all Symbolic icons.

+# We are basically repeating the same rule for every subdirectory, which

+# dependency correctly tied to the image with same name in Symbolic/.
+# I would expect the following to match as a single rule:
+#     %.png: $(top_srcdir)/icons/Symbolic/%.png
+# But it doesn't. If someone knows how, feel free to fix it back into
+# a single rule.
