rdma-core fails to cross build from source and all of the causes relate
to the Python extension build.
A build dependency on python3-dev requests the host architecture
interpreter. It can neither be installed nor run during build. For
building extensions, the typical dependency should be libpython3-dev +
python3-dev:native. Beyond this, cython3 is requested for the host
architecture. It likewise cannot be run that way. While cython3 can have
architecture-dependent behavior and therefore is not marked M-A:foreign,
its use in rdma-core looks ok to annotate the dependency :native.
With these changes, rdma-core successfully builds broken packages. The
Python extensions use suffixes derived from the build architecture. To
fix this, the host's sysconfigdata should be used by exporting the
relevant environment variable during build.
I'm attaching a combined patch for your convenience. Please consider
applying it.
