I agree that cross-compilation is now usable.
Issues related to build and test outside source tree more or less are permanent
but out of cross-compilation scope.
Also parts of patches posted in this issue now are in separate defects or

so here is what I intend to commit.
- --help now does exit with 0 (same as the python script)
- removed the abi safety check (always compares the same
two strings)
- build the script for the build target, so that it can be
checked before installing it.

Great. My only query is whether the changes to sed will work on non-GNU sed.
It used to be like:
sed in out
you've now got:

I'm not saying it won't work, I'm not in a position to check, but I think it's
safer to keep it as it was.

A minor issue: if only --host= is specified on command line but not --build=,

However, configure.ac uses it before that (e.g. the part at the top which looks
for a python interpreter).

A small question about the patch, why this case in the cross_arch function:

That doesn't look correct.
Back to the more important issue of the
support harder, I already get support questions where the
answer depends on the way Python was build and that will likely get worse
with cross-compiling.
I'd be happy to do whatever I can to help out with this. If we could identify
in the build that it was built via cross compilation somehow
