Subject: [PATCH] configure: fix building without isa-l submodule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The isa-l directory is generated automatically by
git on checkout, although it's empty. We check for
that directory existence in order to build ISA-L
and without `git submodule update --init` the build
just fails.

To fix, instead of checking the dir existence, we
check for the autogen.sh file inside that dir.
