Subject: [kvm-unit-tests PATCH] Makefile: Use CFLAGS in cc-option
Date: Fri, 7 Mar 2025 09:39:53 +0100 [thread overview]
Message-ID: <20250307083952.40999-2-andrew.jones@linux.dev> (raw)
When cross compiling with clang we need to specify the target in
CFLAGS and cc-option will fail to recognize target-specific options
without it. Add CFLAGS to the CC invocation in cc-option.
Signed-off-by: Andrew Jones <andrew.jones@linux.dev>
