* gdbarch.sh (gcore_bfd_target): New gdbarch callback.
* gdbarch.h, gdbarch.c: Regenerate. * gcore.c (default_gcore_target): Make return value const. Call gdbarch_gcore_bfd_target if present. (default_gcore_arch, default_gcore_mach): Use target_gdbarch. * corelow.c (core_read_description): Call gdbarch_core_read_description on core_gdbarch instead of current_gdbarch. * ppc-linux-tdep.c (ppc_linux_init_abi): Install gcore_bfd_target.
