+Upstream-Status: Inappropriate [SDK specific]
+
+In order to be able to change the dynamic loader path when relocating
+binaries, the interp section has to be made big enough to accomodate
+the new path (4096 is the maximum path length in Linux).

User mode emulation binaries are linked using a local linker script. The nativesdk ones were not used and the resulting binaries did not have the interp section resized. Hence, those binaries could not be relocated.
