Subject: [PATCH] scons: move host build tool to a proper place
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch aims to move scons host build tool into packages feeds, where
this tools belongs. There are currently no packages in the master tree
which would need scons, yet scons is build always as part of host tools,
just in order to satisfy host build dependency of few packages in the
packages feeeds.

+  SCons is an Open Source software construction tool—that is, a
+  next-generation build 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.
