+Upstream-Status: Inappropriate [SDK specific]
+
+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.
