Using output/host/usr/bin/qmake is indeed the correct way and is
supposed to do the right thing in terms of toolchain and flags and so
on.

Can you clarify exactly what happens?

It has been a few months now, but when I did the Qt5 packaging, I'm
pretty sure I did test a sample Hello World application that was
compiled "out of tree" (i.e not a Buildroot package) with
output/host/usr/bin/qmake. There may have been some regressions/issues
in the mean time, though.
