Subject: [2/6] binutils: relocatable SDK: change PT_INTERP section size
Date: Fri, 27 Jul 2012 11:21:43 -0000
From: Laurentiu Palcu <laurentiu.palcu@intel.com>
X-Patchwork-Id: 33195
Message-Id: <7f3f04caee7e265481f88c333ffae491a9d137db.1343387245.git.laurentiu.palcu@intel.com>
To: openembedded-core@lists.openembedded.org

This patch is needed so that all SDK binaries have the PT_INTERP section
size set to 4096 (max path size in Linux) in order to be able to parse
the binaries later and change the interpreter to the path we want.
