+From f71ecf251f84b4bbc9b7a832d5cd4a8bae95d83b Mon Sep 17 00:00:00 2001

+Subject: [PATCH 01/13] Generate relocatable SDKs
+
+This patch will modify the ELF linker scripts so that the crosssdk
+linker will generate binaries with a 4096 bytes PT_INTERP section. When the binaries
+will be relocated, at SDK install time, the interpreter path can be easily
+changed by the relocating script.
+
+Upstream-Status: Inappropriate [SDK specific]
