removing SVR4 binary compatibilty layer

[Gleb Smirnoff]

  Hello!

  After some discussion on svn mailing list [1], there is intention
to remove SVR4 binary compatibilty layer from FreeBSD head, meaning
that FreeBSD 12.0-RELEASE, available in couple of years would
be shipped without it. There is no intention of merge of the removal.
The stable@ mailing list added for wider audience.

P.S. I account any objector as taker of maintainership :)
