Subject: [PATCH bpf-next v2] tools/runqslower: Fix LDFLAGS and add LDLIBS support
Date: Mon, 22 Jul 2024 17:30:45 -0700 [thread overview]
Message-ID: <20240723003045.2273499-1-tony.ambardar@gmail.com> (raw)
Actually use previously defined LDFLAGS during build and add support for
LDLIBS to link extra standalone libraries e.g. 'argp' which is not provided
by musl libc.
Fixes: 585bf4640ebe ("tools: runqslower: Add EXTRA_CFLAGS and EXTRA_LDFLAGS support")
Signed-off-by: Tony Ambardar <tony.ambardar@gmail.com>
