+/* This function will be the DT_INIT initializer for the ld-linux.so.1

+
+   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.  */
