The lonely two users of do_cmd has gone.
Therefore we can now kill it for good

Previously modules could be build using the make dir/module.ko syntax,
but this has been broken for a while.
Now the directory notation includes modules as well.

I deleted this dependency during the clean-up, but
the this caused caused linking of vmlinux to fail for a
clean build

Added bonus:
1) Check for changed cammandlines performed
2) Nice output with make V=0

In the top-level makefile escaped two lines to avoid launching a second subshell.
This make the build a bit less verbose with make V=0

Patch originally by Jesse Barnes <jbarnes@sgi.com>

Previously the user were required to supply CROSS_COMPILE and ARCH on the
commandline to make, alternatively they patched the Makefile direct.
The following patch allows the user to specify the value of these in
a variable assigned during init or similar.

With make version 3.80 kbuild echo'ed the fixdep command
executed each time a c file was compiled.
This has been tracked down to a bug in version 3.80 of make.
Avoiding newlines in canned command sequences avoid this problem.

At the same time consolidated similar code in Makefile.build,
and avoiding a few ifdef/endif pairs resulting in a more readable makefile.

Patches originally by Adrian Bunk and Rudmer van Dijk.
Included "make V=0|1" and "make C=1"

- no need to #undef CONFIG_IPV6_SUBTREE
- use parentheses around "&" and "|".
- fib_repair_tree() is typo.

- Pointer within an automatic storage class variable fl was illegally
  cached using ip6_dst_store()
- uninitialized saddr was copied to fl.fl6_src
- dont cache if ipv6_saddr_get() failed.

Add C99 initializers to fs/bio.c and fs/dquot.c.  And fs/libfs.c had an
obsolete GCC style initialzers that is converted to C99 style.

smp_send_reschedule_all() is unused in 2.5 and can be eliminated.

It is unused and not needed
