(install-man): Depend upon installdirs. Use

(installdirs): New target.
* 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

into here. Makes insertion into makefiles easier. Also, change
the way that callback.o, gentmap, targ-vals.h, targ-map.c,
targ-map.o, and run are built. They are now built in the
individual simulator directories, taking sources from ../common as
necessary. This replaces the merging of libcommon.a into
linsim.a, which was problematic for the WinGDB build process.
* run.c: Include config.h from . instead of ../common.
* Make-common.in: Remove. It's no longer necessary.
* run.c (main): Explicitly cast malloc() parameter.
This is needed because for certain builds the size field being given
to malloc() is actually 64bits long, and without a cast or malloc
prototype the resulting value used by malloc() depended on the host
endianness, and how long long paramaters are passed into functions.
