From 5c8166419acf468b5bc3e48f928a040485d3e0c2 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 11 Feb 2022 14:14:11 +0900 Subject: kbuild: replace $(if A,A,B) with $(or A,B) $(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched.
