Comment (by ryandesign):

 Great but

 1. since this only fixes a build failure and does not change the
 functionality of existing successful builds on earlier OS versions the
 revision should not be increased;
 2. you must check os.platform before you check os.arch; and
 3. this should be a patchfile not a reinplace for the usual reasons.

 You mentioned in the upstream bug that it may be an autoconf bug. If you
 think so, please file a bug report with them. I have not attempted to
 understand the issue in as much detail as you have and don't currently
 intend to do so; I'm busy with other things.
