SG		 540 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
541 into here. Makes insertion into makefiles easier. Also, change
542 the way that callback.o, gentmap, targ-vals.h, targ-map.c,

544 individual simulator directories, taking sources from ../common as
545 necessary. This replaces the merging of libcommon.a into
546 linsim.a, which was problematic for the WinGDB build process.
547 * run.c: Include config.h from . instead of ../common.
548 * Make-common.in: Remove. It's no longer necessary.
