GDB_OSABI_UNINITIALIZED. * gdbarch.sh: Add osabi to struct gdbarch and to struct gdbarch_info. Include "osabi.h" in gdbarch.c. Check osabi in gdbarch_list_lookup_by_info and in gdbarch_update_p. * gdbarch.c: Regenerated. * gdbarch.h: Regenerated. * osabi.c (gdbarch_lookup_osabi): Return GDB_OSABI_UNINITIALIZED if there's no BFD. (gdbarch_init_osabi): Remove osabi argument; use info.osabi. * osabi.h (enum gdb_osabi): Move to defs.h. (gdbarch_init_osabi): Update prototype. * defs.h (enum gdb_osabi): Moved here. * Makefile.in: Update dependencies. Plus updates to alpha, arm, hppa, i386, mips, ns32k, ppc, sh, sparc, and vax ports to match.
