Ignore change in name of dynamic linker during
execution, on Solaris. This also unbreaks pending breakpoints.
* solist.h (struct target_so_ops): New field same.
* solib-svr4.c (svr4_same): New.
(_initialize_svr4_solib): Register svr4_same.
* solib.c (update_solib_list): Use ops->same, if available.
