/* This function will be the DT_INIT initializer for the ld-linux.so.1
shared object. This is called from rtld.c before shlib initializers.
The old Linux ELF startup code expects the dynamic linker to magically
call atexit to arrange for shared object finalizers to run. (The
ABI-compliant startup code does this itself.) We build a compatible
version of the dynamic linker to install as /lib/ld-linux.so.1, the
name old Linux ELF binaries use. */
