qt5 5.3.2

Version bump for Qt5. I’m currently compiling on Yosemite to see if the
patch in #32093 is necessary still or whether that has been merged into
this release. Whether we want to wait for the Yosemite build to
complete and then patch if necessary, or address that afterwards is up
to the maintainers.

Closes #32093.
