The `KILLCMD' is defined in builtins.c which is generated by `make depend,'
so it's likely that you have stale files left somewhere under
$MAKEOBJDIRPREFIX (which defaults to /usr/obj), or under /usr/src/bin/sh.

Try this command to look for any local modifications or unmanaged files
$ git status

and this one for any ignored files which may be confusing the buildworld.
$ git clean -nx

Replacing -n flag above with -f removes such files for you, but be very
careful not to remove important files.
Alternatively you can move the Git repository to an empty directory and
checkout a clean copy of the source tree there (you can remove src.bak later):
$ cd /usr
$ mv src src.bak
$ mkdir src
$ mv src.bak/.git src/
$ cd src
$ git checkout .	# note the dot at the end; it's not a dust

Now that you've made sure that the source tree is clean, remove /usr/obj
(or whichever directory pointed to by $MAKEOBJDIRPREFIX) and start over.

(well, running `make cleandir' twice should generally cleans up ${.OBJDIR}
and generated files in the current directory, but doing it under /usr/src
may take long time...)

Cheers.
