+Upstream-Status: Inappropriate [SDK specific]
+
+This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings
+and lengths as well as ld.so.cache path in the dynamic loader to specific
+sections in memory. The sections that contain paths have been allocated a 4096
+byte section, which is the maximum path length in linux. This will allow the
+relocating script to parse the ELF binary, detect the section and easily replace
+the strings in a certain path.
