Checked in. No regressions on x86_64.

I only fixed one minor thing, you had a 90 character line in 
sysdeps/generic/ldsodefs.h and I wrapped it down to under 80.

    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.

Cheers,
Carlos.
