> getandroidapilevel-3.patch: Updated version of getandroidapilevel.patch: replace "runtime" with "build time" in the doc :-) Remove also "version > 0" check in support/__init__.py.

LGTM

> About the version > 0 check: would it make sense to add the check in configure.ac? I guess that it was Xavier who wrote the test in support/__init__.py?

The version > 0 check was done because sysconfig.get_config_var() returns 0 when a variable is found as '#undef' in pyconfig.h.  As a reference, the list of the existing API levels with their corresponding Android versions and names:

> I suggest to start to add sys.getandroidapilevel(), and then discuss how to expose (or not) the runtime version.

Agreed and thanks for the patch Victor :)
