Hi Khem,

I make this patch to avoid installing a non-existent buildools-tarball.
If we touch an old buildtools-tarball, the installation would still 
succeed. The touched one is installed.
What would lead to a potential problem is the following situation.
The user built buildtools-tarball, after one day, he modified key part 
of buildtools-tarball recipe, rebuilt it, and then he deliberately 
touched the old one, and then he built an ext SDK.
I don't think that's a situation we need to take care of.
But if you insist that we should, you can suggest a reasonable symlink 
name and I would make a new patch.

Best Regards,
Chen Qi
