misc/compat[789]x ports and sparc64

[Craig Butler]

Hello Folks

I have just noticed that sparc64 arch has been dropped by the
misc/compat7x,8x,9x ports.

I currently use compat7x for some older software on a few jails.

Further investigation show that the older distfiles for 7x and 8x are
available for sparc64.

Is it worth updating them, creating a 9x for sparc64, then sending pr to
the port maintainer ??  or has it been dropped for a reason ?

Regards
