Unbreak net/bro on macppc (was: Re: powerpc bulk build report)

Hi ports,

> http://build-failures.rhaalovely.net//powerpc/2019-02-04/net/bro.log

It requires libatomic. According to what i read in the ports tree, hppa
would need that as well, so i added it.

It builds fine on macppc [1], i've seen nothing wrong during runtime as
well, but i've nothing fancy to monitor tbh.

Any comments?

Charlène.
