The genl code uses constructs which violate the strict aliasing
constraints of gcc 4.4. Disable the optimization to avoid warnings
and potential breakage.
The iptables code supports a "no shared libs" mode where it can be used
without requiring dlfcn related functionality. This adds similar support
to iproute2 so that it can easily be used on systems like nommu Linux (but
obviously with a few limitations -- no dynamic plugins).
Rather than modify every location that uses dlfcn.h, I hooked the dlfcn.h
header with stub functions when shared library support is disabled. Then
symbol lookup is done via a local static lookup table (which is generated
automatically at build time) so that internal symbols can be found.

The current genl Makefile sticks -lm and -ldl into LDFLAGS ... however, this
does not create the proper link order as the implicit Makefile rules will
place LDFLAGS before object files
attached patch uses LDLIBS for -lm and -ldl and make's implicit rule will
place them in the proper location
also, i removed the -s argument to `install` as install does stripping
improperly in many scenarios (such as cross-compiling) ... and in general,
it's nice if the decision to strip is handled by the sysadmin

The controller is the only module using this at the moment.
Thomas has a sample user of genetlink that would fit here; bug him
for it.
