fix it in the other way then.

you just completely broke everything there didnt you?

how will the _init/_fini code of executables with
DT_INIT, DT_FINI dynamic tags run?

i think gcc still havent fixed weak object symbol alias
bugs with lto so e.g. you will get incorrect environ if
you lto link the libc.
