From 6e0839fda3f8598b164a7f23f3eec039e2db5fbc Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 14 Mar 2021 15:15:50 +0900 Subject: 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.
