From cccb2d76c5ec5088e52c7913801a4bbd6661945b Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sun, 9 Feb 2020 12:09:18 +0100 Subject: arch/arm64/Makefile.inc: Avoid # in variable definition Interpretation if # starts a comment inside a variable definition varies between GNU make versions. Use a wildcard to match the first # and use `sed` instead of `grep | cut` to avoid unbalanced quoting chars. Tested with GNU make 4.2.1 and 4.3. Both produce the same output as 4.2.1 did before the patch.
