Re: pkg/53411: net/bind910 fails on mac68k

[Tero Kivinen <kivinen%iki.fi@localhost>]

This same problem is still present in the net/bind914 on the i386
(32-bit) environment. On amd64 you will not see it.

At least on i386 you can make it work by using gcc5-libs package,
which contains the libatomic.so. You do that by adding following patch
to the net/bind914/options.mk and then adding

PKG_OPTIONS.bind914=latomic

to mk.conf.

I added separate option for latomic, mostly because I am not sure
if this problem really is in every 32-bit platform or not, and how to
perperly test whether this platform is 32-bit or not. Compiling the
gcc5-libs takes quite a lot of time, so we do not want to do that
unless it is really needed...
