[rfa] alpha sjlj vs pointer mangling

[Roland McGrath]

If it doesn't use the thread pointer, then the PTR_MANGLE defn belongs in a
generic alpha file (create sysdeps/alpha/sysdep.h I guess).

We don't.  There is no particular harm in those modules getting the
DT_NEEDED for ld.so's soname, so I wouldn't bother avoiding it.
