Bug#950790: libqt5qml5: Do a double build with SSE2 enabled on i386

[Lisandro Damián Nicanor Pérez Meyer <lisandro@debian.org>]

Package: libqt5qml5
Version: 5.12.5-5
Severity: normal

Lars pointed out [1] that QtQml (and so I guess this lib, will need to double
check) would really benefit from a i386 build with SSE2 enabled.
