From b513adf45c9bca9222a0533e0c412b66350a8ab5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 19 Feb 2019 18:33:06 +0900 Subject: [PATCH] scripts/gdb: refactor rules for symlink creation gdb-scripts is not a real object, but (ab)used like a phony target. Rewrite the code in a more Kbuild-ish way. Add symlinks to extra-y and use if_changed.
