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.
