Okay, so it appears the issue can be resolved by pre-setting LDFLAGS with the following and then rebuilding vim:

$ export LDFLAGS="-rdynamic"

It appears to successfully resolve the symbol reference I was having issues with.

Curiously, a brief look at if_python3.c implies the Python 3 library is treated as a shared library (which could be totally wrong as I haven't dug any deeper).
However, the actual library that's linked is static (although, this may be quite normal).
