/* 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. */
