If you cross build for x86_64, you *must* use cygport from the git repo
for now.  With the stock version you end up with a 32 bit build.

cygport is easy to build.  Nevertheless, Yaakov, any chance you could
update the 32 bit and the Fedora cygport, too?  If it's not asked too
much, preferredly with a fix so that the dist files are not copied
to the toplevel, but only reside in the dist subdir...

It shouldn't since the package just doesn't exist.
