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.

+Upstream-Status: Inappropriate [SDK specific]
+

+binaries, the interp section has to be made big enough to accomodate
+the new path (4096 is the maximum path length in Linux).
