* configure: Re-generate.

        * Make-common.in (CSEARCH): Do not include the gdb directory in
        the search path.
        * Make-common.in (SIM_ENDIAN, SIM_HOSTENDIAN, SIM_INLINE,
        SIM_WARNING): Drop, requiring the simulator specific Makefile.in
        to explicitly incorporate these.

        * aclocal.m4 (--enable-sim-alignment); New option. Strongly
        specify the alignment restrictions of the target architecture -
        without this option all alignment restrictions are accomodated.
        (--enable-sim-assert): New option.  Conditionally compile in
        assertion statements.
        (--enable-sim-float): New option. Strongly specify the target's
        floating point support.
        (--enable-sim-hardware): New option.  Specify the hardware devices
        included in the simulation.
        (--enable-sim-packages): New option.  Specify the hardware
        packages included in the simulation.
        (--enable-sim-regparm): New option.  Specify that parameters be
        passed in registers instead of on the stack.
        (--enable-sim-reserved-bits): New option. Specify that reserved
        bits within an instruction are are correctly set.
        (--enable-sim-smp): New option. Specify the level of SMP support
        to be included in the simulator.
        (--enable-sim-stdcall): New option.  Specify an alternative
        function call convention.
        (--enable-sim-xor-endian): New option.  Configure xor-endian
        support used by some targets to implement bi-endian support.
