I can provide a server for you to upload to.  Git tags for 
versioning might be interesting for uploads, but they're not 
going to be binaries that will stay around for too long.

This is a bastardized version of the git gcc-descr alias.

git describe --all --abbrev=40 --match 'basepoints/gcc-[0-9]*' 
origin/master | sed -n 's,^\(tags/\)\?basepoints/gcc-,r,p'

That should get you a tag like 
r11-3179-g5de41c886207a3a0ff1f44ce0a5a644e9d9a17f8
