Changes to enable building on Solaris, FreeBSD

Browse Source 
Solaris (SmartOS) build needs alternative solutions to two termios
things, plus makefile support for additional link libraries.  PNC
support is untested and is likely _very_ slow, since Solaris doesn't
have O_ASYNC.  The usual suggestion is to rewrite such code to use
poll().

Incidental: utilities makefile needed tabs to make `make` happy
on FreeBSD.  Which make?  Don't remember now.
