thunderbird-i18n fails to extract | framework extract regression?

[Matthias Andree]

I get this extract failure when trying to build thunderbird-i18n
24.3.0_1 from an up-to-date ports tree on 9.2-RELEASE amd64:

EXTRACT_CMD is /usr/bin/tar.  Adding USES=zip:infozip to the port's
Makefile appears to fix this, but this might be a regression in the
framework that portmgr@ should investigate.

And I do seek out portmgr@ to deal with matters way more carefully.

We have had too many framework breakages recently, and I have a feeling
that we have been rushing many changes of the "should work" category
that would have required an -exp run...
