7120         targ-map.o, and run are built.  They are now built in the
7121         individual simulator directories, taking sources from ../common as
7122         necessary.  This replaces the merging of libcommon.a into
7123         linsim.a, which was problematic for the WinGDB build process.
7124         * run.c:  Include config.h from . instead of ../common.
7125         * Make-common.in:  Remove.  It's no longer necessary.
