5763         targ-map.o, and run are built.  They are now built in the
5764         individual simulator directories, taking sources from ../common as
5765         necessary.  This replaces the merging of libcommon.a into
5766         linsim.a, which was problematic for the WinGDB build process.
5767         * run.c:  Include config.h from . instead of ../common.
5768         * Make-common.in:  Remove.  It's no longer necessary.
