From 95c99f69e026e8c57aecba545e51c97f3b284e75 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove a BSD-ism.
CTRL('L') is a BSD-ism. CTRL() is defined in sys/ttydefaults.h
which does not always exist. Instead of adding scons tests for
needing CTRL() and its include files just replace with a simple
constant.
Needed for musl and found by Baruch Siach <baruch@tkos.co.il>
