[gforth] Socket code

[John Chludzinski]

As a gforth newbie I went online and downloaded sock.fs and tcpserver.fs 
from GitHub. Tried putting the shabang: #! /usr/bin/gforth in the file 
and ruuning it. I have an x86-64 box running Fedora 23.

For socket.fs I got:

sh: --silent: command not found

in file included from *OS command line*:-1
socket.fs:47: libtool compile failed
> > > end-c-library<<<
Backtrace:
$7F627B8AB988 throw
$7F627B8E7788 c(abort")
$7F627B8E8390 compile-wrapper-function1

For tcpserver.fs I got:

in file included from *OS command line*:-1
in file included from /home/john.chludzinski/tcpserver.fs:11
in file included from /usr/share/gforth/0.7.3/lib.fs:21
/usr/share/gforth/0.7.3/libffi.fs:159: libtool compile failed
> > > end-c-library<<<
Backtrace:
$7F9EE535C988 throw
$7F9EE5398788 c(abort")
$7F9EE5399390 compile-wrapper-function1

This "libtool compile failed" seems to be the issue.
