Subject: [PATCH] selftests: use "$(MAKE)" instead of "make" for headers_install
Date: Mon, 17 Aug 2020 17:09:46 +0200	[thread overview]
Message-ID: <20200817150946.21477-1-dvlasenk@redhat.com> (raw)

If top make invocation uses -j4 or larger, this patch reduces
"make headers_install" subtask run time from 30 to 7 seconds.
