* aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.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.
