It depends on what system and build tools that you are using and that
the Python you are using was built with but, in general on most
POSIX-like systems, one way to do it should be to supply it via an
LDFLAGS environment variable. The safest approach would be to get the
default value of LDFLAGS for this Python instance, append your
additional values to it, and pass it back into the setup.py build. You
can do that all in one line:
LDFLAGS="$(python -c 'import
sysconfig;print(sysconfig.get_config_var("LDFLAGS"))')
-Wl,--allow-shlib-undefined" python setup.py build
