SG		 3391 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
3392 into here. Makes insertion into makefiles easier. Also, change
3393 the way that callback.o, gentmap, targ-vals.h, targ-map.c,

3395 individual simulator directories, taking sources from ../common as
3396 necessary. This replaces the merging of libcommon.a into
3397 linsim.a, which was problematic for the WinGDB build process.
