Mark Kettenis 05816f706e * osabi.c: Include "gdb_assert.h" and "gdb_string.h".
(struct gdb_osabi_handler): Remove member `arch'.  Add member
`arch_info'.
(gdbarch_register_osabi): Add new argument `machine'.  Use ot to
construct a `struct bfd_arch_info' and store it in the `struct
gdb_osabi_handler' that is created.
(gdbarch_init_osabi): Check for compatibility based on machine
type and architecture.
* osabi.h (gdbarch_register_osabi): Adjust prototype and update
comment.
* alpha-linux-tdep.c (_initialize_alpha_linux_tdep): Add 0 as
second argument in call to gdbarch_register_osabi.
