I haven't done this myself but I am aware of two things:
- https://sourceware.org/gdb/wiki/CrossCompilingWithPythonSupport
- The patch discussed at
https://sourceware.org/legacy-ml/gdb-patches/2012-12/msg00754.html
claims to improve cross-compiling with python (Debian used to carry
that patch, though they've since dropped it)
