Continuing the removal of 'current_program_space->core_bfd ()' from GDB, this commit updates two gdbarch methods: gdbarch_core_xfer_shared_libraries gdbarch_core_xfer_shared_libraries_aix to take the core file BFD as a reference parameter. For now this just moves the 'current_program_space->core_bfd ()' calls up the program stack into core_target::xfer_partial. In the future I plan to move the core file BFD object out of the program_space and into the core_target, at which point these new global accesses can also be removed. There should be no user visible changes after this commit. Approved-By: Simon Marchi <simon.marchi@efficios.com>
