Previously, the script was caching any file already present in the
destination directory, regardless of its origin. This caused issues
when the directory contained files copied from external sources like autoreconf --install.
For example:
./autogen.sh --install copies config.guess and config.sub
from the system to ./tool.
ruby tool/downloader.rb -d tool -e gnu config.guess config.sub
treats those files as if they were downloaded and caches them.
Removing the files: rm tool/config.guess tool/config.sub.
Running the downloader again, it mistakenly restores the cached
files instead of downloading fresh versions.
