Subject: [PATCH iproute2-next] Rerun configure when it is newer than config.mk
Date: Sat, 15 May 2021 14:20:09 -0600 [thread overview]
Message-ID: <20210515202009.8904-1-dsahern@kernel.org> (raw)
config.mk needs to be re-generated any time configure is changed.
Rename the existing make target and add a check that the config.mk
file needs to exist and must be newer than configure script.
