Since the conversion of Qt to GENTARGETS in
421cda1fd0, plugin installation could
break in some situations, for example if SQL support was enabled, but
without any SQL driver: the sql plugin directory doesn't exist, but
our qt.mk wanted to copy it.
This patches simplifies the plugin handling a bit, and basically
copies all Qt plugins installed in the $(STAGING_DIR) to the
$(TARGET_DIR), assuming Qt has only built and installed the needed
plugins.
Moreover, instead of installing plugins to usr/plugins, which is a odd
location, we install them in usr/lib/qt/plugins. This requires a small
patch to Qt ./configure script so that even when -hostprefix is used,
the -plugindir option is taken into account.
