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.

In iproute2 package, the updates of UAPIs files are performed
after the needed feature lands in kernel's net-next tree.
Such development flow created delays to the rdma tool developers,
who uses rdma-next tree as a basis for their work.
Move RDMA UAPI file to be under rdma/ folder, so whole responsibility
of syncing this file will be on them.

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

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.

RDMA devices are cross-functional devices from one side,
but very tailored for the specific markets from another.
Such diversity caused to spread of RDMA related configuration
across various tools, e.g. devlink, ip, ethtool, ib specific and
vendor specific solutions.
This patch adds ability to fill device and port information
by reading RDMA netlink.
