dcb, devlink, rdma, tipc and vdpa rely on libmnl to compile, so they
check for libmnl to be installed on their Makefiles.
This moves HAVE_MNL check from the tools to top-level Makefile, thus
avoiding to call their Makefiles if libmnl is not present.

On some systems we fail to link because of missing math lib.
add -lm to devlink.

This little dance of mnl_socket_open(), option setting, and bind, is the
same regardless of tool. Extract into a new module that should hold helpers
for working with libmnl, mnl_util.c.

When performing make install in iproute2 (current git master),
if $(HAVE_MNL) is not selected, some Makefiles try to call
install with an empty target, which causes a non-critical make error.

Leaving a variable with a generic name such as TARGETS undefined would lead
to Make picking up its value from the environment. Avoid this by always
defining TARGETS in the Makefiles.

For all files in iproute2 which do not have an obvious license
identification, mark them with SPDK GPL-2

This renames Config to config.mk and includes more Make input.
Now configure generates all the required CFLAGS and LDLIBS for
the optional libraries.
Also, use pkg-config to test for libelf, rather than using a test
program. This makes it consistent with other libraries.

Similar to the Linux kernel and perf add infrastructure to reduce the
amount of output tossed to a user during a build. Full build output
can be obtained with 'make V=1'
