+From c9aed4cb3c02715b2ba1fc70949043849f202f46 Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+Date: Sun, 8 Dec 2019 00:31:35 -0800
+Subject: [PATCH] binutils-crosssdk: 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]
