kbuild: rename hostprogs-y/always to hostprogs/always-y

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.

It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.

This commit renames like follows:

  always       ->  always-y
  hostprogs-y  ->  hostprogs

So, scripts/Makefile will look like this:

  always-$(CONFIG_BUILD_BIN2C) += ...
  always-$(CONFIG_KALLSYMS)    += ...
      ...
  hostprogs := $(always-y) $(always-m)

I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.

The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

When there is no suitable special rule, and the host program
shall be built when a makefile is entered, the $(always)
shall be built when a makefile is entered, the always-y
variable shall be used.
Example::
#scripts/lxdialog/Makefile
hostprogs-y := lxdialog
always := $(hostprogs-y)
hostprogs := lxdialog
always-y := $(hostprogs)
This will tell kbuild to build lxdialog even if not referenced in
any rule.
4.6 Using hostprogs-$(CONFIG_FOO)
---------------------------------
A typical pattern in a Kbuild file looks like this:
Example::
#scripts/Makefile
hostprogs-$(CONFIG_KALLSYMS) += kallsyms
Kbuild knows about both 'y' for built-in and 'm' for module.
So if a config symbol evaluates to 'm', kbuild will still build
the binary. In other words, Kbuild handles hostprogs-m exactly
like hostprogs-y. But only hostprogs-y is recommended to be used
when no CONFIG symbols are involved.
5 Kbuild clean infrastructure
=============================
"make clean" deletes most generated files in the obj tree where the kernel
is compiled. This includes generated files such as host programs.
Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always),
$(extra-y) and $(targets). They are all deleted during "make clean".
Files matching the patterns "*.[oas]", "*.ko", plus some additional files
generated by kbuild are deleted all over the kernel src tree when
"make clean" is executed.

Additional files or directories can be specified in kbuild makefiles by use of
$(clean-files).
