[perl #60068] [BUG] t/pmc/packfile.t: set_integer_keyed_str test failing on Darwin PPC

[James Keenan via RT]

Tonight, for the first time in four weeks, this test (#6) passed on
Darwin/PPC.  Cf.:
http://smolder.plusthree.com/app/public_projects/tap_stream/8270/260

I can't really tell which commit fixed this failure.  Given the fact
that several files with 'pack' in their names were changed in r32888
(particle changing PARROT_API -> PARROT_EXPORT), that commit is a
possibility.

Assuming it continues to pass over the next week, I will close the ticket.
