Add ravenscar-thread support for powerpc.
gdb/ChangeLog:
* ppc-ravenscar-thread.h, ppc-ravenscar-thread.c: New files.
* Makefile.in (ALL_TARGET_OBS): Add ppc-ravenscar-thread.o.
(HFILES_NO_SRCDIR): Add ppc-ravenscar-thread.h.
(ALLDEPFILES): Add ppc-ravenscar-thread.c.
* configure.tgt: Add ravenscar-thread.o and ppc-ravenscar-thread.o
to gdb_target_obs for every target that uses rs6000-tdep.o.
* rs6000-tdep.c: #include "ppc-ravenscar-thread.h".
(rs6000_gdbarch_init): Call register_e500_ravenscar_ops
or register_ppc_ravenscar_ops.
