* simops.c: Fix register extraction for a two "movbu" variants.
...
Somewhat simplify "sub" instructions.
Correctly sign extend operands for "mul". Put the correct
half of the result in MDR for "mul" and "mulu".
Implement remaining instructions.
Tweak opcode for "syscall".

* 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.
