SG		 2530 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
2531 into here. Makes insertion into makefiles easier. Also, change
2532 the way that callback.o, gentmap, targ-vals.h, targ-map.c,

2534 individual simulator directories, taking sources from ../common as
2535 necessary. This replaces the merging of libcommon.a into
2536 linsim.a, which was problematic for the WinGDB build process.
2537 * run.c: Include config.h from . instead of ../common.
2538 * Make-common.in: Remove. It's no longer necessary.
