[PyQt] ANN: pyqtdeploy v2.0 Released

[Patrick Stinson]

Phil,

There is a current bug in building python (maybe 3.5.2 - 3.6.4?) for iOS which does not correctly #undef HAVE_SYSTEM or #define HAVE_SYSTEM 0 around Modules/posixmodule.c:200 for v3.5.2 or Modules/posixmodule.c:180 in v3.6.4 , causing a compile error (see below). In the past I had to edit this file manually before the build phase, which worked fine because the build phase was separated from the configure/qmake phase. But, it seems like pyqtdeploy-sysroot v2 might need to patch the file to accomplish this? Or maybe there is a better way?
