* m68k-tdep.h (enum struct_return): Define.
(struct gdbarch_tdep): Add struct_return.
* m68k-tdep.c (m68k_push_dummy_call): Non-scalars bigger than 4
bytes are padded to the right, not to the left. Pass struct value
address in register %a1, not on stack.
(m68k_use_struct_convention): New function.
(m68k_gdbarch_init): Set use_struct_convention. Initialize
struct_return in tdep to pcc_struct_return.
* m68klinux-tdep.c (m68k_linux_init_abi): Set struct_return to
reg_struct_return.
