    kbuild: rename hostprogs-y/always to hostprogs/always-y · 5f2fb52f
    Masahiro Yamada authored
    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.
