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.
