File ldd-system-interp.patch of Package glibc.10713
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.
