[Buildroot] [PATCH 2/2] qt: speed up qmake build

[Thomas Petazzoni]

qmake is built during the execution of Qt ./configure script, so it is
built just with a normal make, not taking advantage of parallel
compilation. Passing MAKEFLAGS=-j$(BR2_JLEVEL) allows to speed up the
qmake compilation process quite a bit.
