[Harald Sitter]

Git commit d16b722fa5f364285ad41b8db1d38b289fd76276 by Harald Sitter.

Pushed by sitter into branch 'Neon/release'.

add support for letting qtchooser fall into command not found

...using the full path of the default sdk

this then allows us to provide cnf data that feeds into the c-n-f
database and gets printed when the backing binary is not present

e.g. qmlscene gets resolved to /usr/lib/qt5/bin/qmlscene and we have
that in our cnf data mapped to qmlscene so then qtchooser tells the user
to install qmlscene, the package
