Log Message:
Add a workaround so that po4a's use of GetTerminalSize() from
Term::ReadKey doesn't end up doing tty i/o, which will in all
probability stall a bulk build if it's started on a tty, and
no special steps are taken to disassociate the bulk build job
from the tty.

It appears that later versions of po4a does not suffer from
this problem, so this is a minimal fix suitable for pull-up.

Bump package revision.
