When Jenkins tries to generate my emulator, it errors out with:

tools/android create avd -f -a -c 256M -s 1080x1920 -n hudson_de-DE_480_1080x1920_Google_Inc._Google_APIs_23_x86 -t "Google Inc.:Google APIs:23" --abi x86
Error: Invalid --tag default for the selected target.

But tools/android list targets outputs

id: 6 or "Google Inc.:Google APIs:23"
 ...
 Tag/ABIs : google_apis/x86

Back when I implemented support for ABI tags, I seem to recall it being impossible to discover the correct tag in every single case, but from this report, it should be seemingly simple enough to determine automatically choose the correct tag for this case at least.
I can't remember what the implementation looks like, and I haven't looked at the code to see whether we're already doing something similar.
