Subject: [PATCH 1/2] scripts: get_abi.pl: fix fallback rule for undefined symbols

The rule that falls back to the long regex list is wrong:
it is just running again the same loop it did before.

change it to look at the "others" table.

That slows the processing speed, but provides a better
list of undefined symbols.
