It looks like the only place wchar support is used is in a couple
spots in sftpclient in the interactive output handling where somebody
is trying to keep things pretty by checking how many display columns
will be occupied by a filename before it's printed using
printf(). [For example in the output of the the "ls" command built in
to the client, it tries to figure out how many columns of filenames to
print, and how to pad them to keep things aligned.]

The server doesn't need wchar support at all.

So the easiest option for me is probably to change the .mk file to
just build/install the server and not the client. I suppose the proper
thing to do would be to change the Config.in file so that building the
client is optional and wchar support is only required when the client
is built.

Or I could patch the client so that if libc doesn't have wchar
support, it assumes that number_of_columns(filename) ==
strlen(filename). People without wchar support who use UTF8 filenames
would have to tolerate columns that don't line up in the output from
the "ls" command.
