After 8b3c67690c4747b9fadfef407e6261524fb03f8a the `make install`
command fails if docs are not disabled through CFG_DISABLE_DOCS,
because now the `install` target uses
../../tmp/dist/$(DOC_PKG_NAME)-$(CFG_BUILD)/install.sh
In 714a2c678c5a5d1fdb9d6de3d515279120305441 the `prepare_install`
target wwas changed to conditionally depend also on the doc archive,
but did not modify `prepare_uninstall`.
Instead of explicitly depending on
dist/$(PKG_NAME)-$(CFG_BUILD).tar.gz, the `prepare_[un]install`
targets now depend on `dist-tar-bins`, which packages the appropriate
dist archives depending on the configuration.
