Hi Yann,
Sorry to be annoying, but...

Still not true for moc :-)

Perhaps it would be better to handle the $(HOST_DIR) / $(O) combination here, so:
if [ -d $(2)/$(HOST_DIR) -o -d $(2)/$(O) ]; then \

You never replied to my comment that I think this would fit better directly in
the .stamp_install_* rules rather than as hooks. My reasoning is that it is much
more difficult to find out why some commands are being called when they're
hidden in hooks. That's not too bad for things like gathering statistics since
they're supposedly inobtrusive, but here you're throwing an error so it is
really useful to be able to find easily in the source where this error comes from.
