Thanks a lot for looking into this!

However, there is one thing that this doesn't seem to address: the
installation part.

Currently, the staging installation is just:

	make install

with no DESTDIR/INSTALL_ROOT, and therefore for the target
installation, we have to manually install libraries, QML files and
other stuff, which is really annoying to maintain. Ideally, we would
like Qt5 to behave like most other packages, and do:

	make INSTALL_ROOT=$(STAGING_DIR) install

for the staging installation, and:

	make INSTALL_ROOT=$(TARGET_DIR) install

for the target installation. This change is not strictly needed for
per-package host/target directories, but I really would like to take
the opportunity of changing all this Qt5 logic to also address this
related problem.

I had prepared something like this:
https://github.com/tpetazzoni/buildroot/commit/05e776abf531319a749f5a7d65f265979ea6c4ab,
but I don't remember if it was working completely or not.

Thanks,

Thomas
