Configure was finding the host's python, and then trying to link
against some python library and failing because the cross-compiler
cannot link with the host's libraries.

With the patch I sent and explicitly disabling python it

Well, if it doesn't cause any problem, please apply the patch.  That
was all I needed to get it cross-compiling.
