This a customized MinGW build of Qt 5.5.1 derived from Fedora's mingw-qt 5.5.0 packages
(https://apps.fedoraproject.org/packages/s/mingw-qt5).
The following changes have been made:

- Adjusted and removed patches as required by Qt 5.5.1.
- Set OpenGL flavor to desktop, reason: sufficient, less files to deploy, less build dependencies.
- Disabled ICU, reason: not needed, and many MB of files less to deploy, less build dependencies.
- Disabled SSL, reason: not needed, less build dependencies.
- Disabled DBus, reason: not needed, less files to deploy, less build dependencies.
- Disabled ODBC, reason, not needed, less build dependencies.
- Enabled system proxy usage, reason: we don't provide a configuration feature.
