[PATCH v4 0/3] Rework exception handling in the dynamic loader [BZ #25486]

[Florian Weimer]

This is a rebase on the current tree.  No real changed compared to the
previously posted version.  This change is a pre-requisite for moving
more loader functionality into ld.so.

Tested on x86_64-linux-gnu.

Thanks,
Florian

Florian Weimer (3):
  ld.so: Export tls_init_tp_called as __rtld_tls_init_tp_called
  scripts/localplt.awk: Handle DT_JMPREL with empty PLT (for C-SKY)
