#     kbuild: replace sed with $(subst ) or $(patsubst )
#     
#     For simple text replacement, it is better to use a built-in function
#     instead of sed if possible. You can save one process forking.
#     
#     I do not mean to replace all sed invocations because GNU Make itself
#     does not support regular expression (unless you use guile).
#     
#     I just replaced simple ones.
