From 95bde2a4ae4a92e984a5783ca1f09f44bf04fadb Mon Sep 17 00:00:00 2001
From: Baruch Siach <baruch@tkos.co.il>
Date: Thu, 19 Apr 2018 12:28:11 +0300
Subject: [PATCH] lib: allow to disable shared libraries
Just like BUILD_STATIC=no disables static libraries, BUILD_SHARED=no
disabled shared libraries. This is useful to support toolchains that do
not support shared libraries.
