BUG: wrong "awaiting parents" in flang migration

[h-vetinari]

So the flang migration is unusual in several ways:

• we haven't migrated a compiler pin in a long time
• it's the first migration using platform_allowlist:
• it has a specific piggyback migrator (I expect this to be less relevant, but still)

It's possible that there's some unexpected interplay there somewhere. In any case, the two biggest open feedstocks for the migration (mpich & openmpi) both are shown as "awaiting parents", even though all their parents have been done.

Thanks. The bot might take some time to catch up, especially if the feedstocks have changed and the bot missed push events for rebuilding the links.

I get that, which is why I generally wait 24-48h. The only parent I can find according to the bot metadata was merged weeks ago though...
