This allows libc.so to run the C runtime initializer as soon as the dynamic linker loads the shared library, i.e. before any other initializers (e.g. static C++ constructors in other shared libraries the executable depends on). This also removes the bug where the initializers from the executable itself were run twice: once by the dynamic linker, and another time by __libc_init as defined by libc_init_dynamic.c
