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.
