[OE-core] [PATCH 2/6] binutils: relocatable SDK: change PT_INTERP section size

[Laurentiu Palcu]

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.
