we still run into this issue when building for Ubuntu and the answer is that they pass -Bsymbolic-functions and this means that the internal calls to gprs_ns_sendmsg are linked directly so we can not interpose.

Your change forces static linking so the gprs_ns_sendmsg is resolved differently and allows us to interpose one way or another. The issue with -static is that we now have an optional static build.

I am tempted to just put LDFLAGS := $(LDFLAGS:-Wl,-Bsymbolic-functions=) into the debian/rules. The library will not perform worse than on other platforms.

The other architectural change is to be able to "plug" transport so we can provide our own send functions.
