scons_4_1_0: detach from sconsPackages

This is probably a legacy release, since I have found no other package using it.

+      SCons is an Open Source software construction tool. Think of SCons as an
+      improved, cross-platform substitute for the classic Make utility with
+      integrated functionality similar to autoconf/automake and compiler caches
+      such as ccache. In short, SCons is an easier, more reliable and faster way
+      to build software.
