The backport of #13150 to the 2.7 branch breaks the build on darwin. There is a special case for providing the _sysconfigdata module in _generate_posix_vars before get_platform is called (darwin only) and before the module is actually written.
However get_platform is called before, in site.addbuilddir(). Wondering if this call can either be avoided, or worked around.
options:
- backport issue586680 too (http://hg.python.org/cpython/rev/4742e7aea2f5/)
- fall back to generic values for osname, release, machine
any other options?
