This patch adds support for stepping into/over the PLT stubs generated
for secure PLT on PowerPC 32. It requires a recent binutils which
generates symbols for the stubs.

This has been tested on PowerPC 32-bit systems with and without PAX.

2012-01-17 Michael Eager <eager@eagercon.com>

* configure.tgt (powerpc-*-linux*): Add glibc-tdep.o.
* ppc-linux-tdep.c: Include glibc-tdep.h.
(powerpc32_plt_stub, powerpc32_plt_stub_so): Add PLT stub templates.
(powerpc_linux_in_plt_stub): New function.
(powerpc_linux_in_dynsym_resolve_code): New function.
(ppc_skip_trampoline_code): New function.
(ppc_linux_init_abi): Use PPC specific functions rather than generic.
Use glibc_skip_solib_resolver.

Will check in in a couple days, unless I hear additional comments.
