glibc/ldd-system-interp.patch

Never try to execute the file in ldd

Executing a random file is never a good idea.  Treat all arguments as if
they are invoked with __libc_enable_secure, and run them through the known
good dynamic linker.

	* elf/ldd.bash.in: Always run through the dynamic linker, even if
	the file has its own interpreter.
