Many ports recently marked BROKEN/unfetchable that aren't broken?

[Nick Rogers]

Hello,

I'm not sure if this belongs in a bug report or not, but it seems that a
recent commit marked many ports BROKEN with reason "unfetchable". However,
I don't seem to have a problem fetching and building them if I remove the
BROKEN declaration.

The commit was:

Mark a few ports BROKEN (unfetchable)
------------------------------------------------------------------------

But "a few" is actually closer to 300...

For me the affected ports were sysutils/pftop, sysutils/zfs-stats, and
sysutils/stress, which worked just fine before this commit. Apologies if I
am missing something, but it seems like they are not actually broken?

Thanks,
-Nick
