In SPDK, we will build isa-l with no shared option
and then integrate it into SPDK. And we do not need
to install isal in the system libaries.
Note: ocf build in autobuild.sh now needs to build
include/spdk/config.h before building the ocf library,
to ensure that header is available in a clean build
environment.

This allows us to remove $(ENV_LINKER_ARGS) from all of the

Modify spdk.unittest.mk to explicitly set ENV_LINKER_ARGS
to nothing, to avoid DPDK libraries from getting linked
into unit tests. This seems better than creating separate
LINK_C rules for unit tests. Provide a UNIT_TEST_LINK_ENV
flag to allow select unit tests to override this behavior -
it's needed for some of the env unit tests.

We have hairy configuration method. First configure script uses CONFIG,
environment and arguments to produce CONFIG.local and config.h then
makefile uses CONFIG, environment and CONFIG.local to produce config.h
again. First time config.h can't be generated reliably as config.h
target in Makefile is passing MAKEFLAGS and they are unknown at
configuration phase.
Lets remove this mess by producing final mk/config.mk file and get rid
of CONFIG.local. This will also generate full build configuration in one
file instead scattering them in CONFIG and CONFIG.local.
In next patch scripts/genconfig.py can be removed.
