From 46454ac2a8a7d693ac135f0d4a9461bbcf24eea9 Mon Sep 17 00:00:00 2001
From: Thomas Martitz <kugel@rockbox.org>
Date: Tue, 24 Aug 2010 12:38:42 +0000
Subject: Move setjmp to lib and add setjmp for sh (imported from newlib) and
 compile it as separate library.

It's used by both, plugins and codecs, and sh/hwcodec doesn't compile codecs
so it doesn't fit into sources.
