Don't use broken DL_AUTO_FUNCTION_ADDRESS()
On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.
