* Fix a bug with a configuration in which the shell's kill builtin
would be mistreated as a killall command (i.e. '-q' works, and
'kill process_name' succeeds when it shouldn't):
CONFIG_ASH_JOB_CONTROL=y
CONFIG_HUSH_KILL=y
# CONFIG_KILL is not set
CONFIG_KILLALL=y
# CONFIG_KILLALL5 is not set
* Optimize out unneeded code when the relevant applets are not
selected.
* Move kbuild lines about shells' kill builtins from Kbuild.src to
kill.c, to accompany the new HAVE_SH_KILL macro. I hope this would
make maintanence a little bit easier.
