[Buildroot] [git commit] python-crossbar: propagate missing dependencies

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=b5ac4b329f4fb913715e0941e4cca6e889ed643c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

python-crossbar selects python-msgpack which selects msgpack, which
depends on C++ and 4-byte __sync intrinsics. But python-crossbar does
not have the dependencies propagated.

Fixes:
