qt4: allow a reduction in build time

When reducing build time by adding QT_DISTRO_FLAGS from the set '-no-gui -nomake tools
-nomake examples -nomake demos -nomake docs', build failure can occur, due to not building
all tools.

* Make rm not error out when removing one of the, possibly, non-existing tools.
* Only try to rename qtdemo, if qtdemo exists.
* Check if the phrasebook path exists, and only then call do_split_packages()
