No, it won't, (at least for you to be able to use tcpserver, lshd
would have to accept to handle one session from stdin/stdout and then
exit, which it doesn't).

If you just want to use the wrapper functionality of tcpserver (and
don't want to use tcpwrappers instead), you could let your lshd listen
on a local interface and have tcpserver run a program that just sets
up a tcp connection to lshd and copy data from/to stdin/out to/from
the network (tcpcat seems to be suitable, netcat and tcpconnect are
other alternatives).

This seems rather strange, considering that it's lsh (not lshd) you're
building, and it shouldn't really have need anything from libwrap, but
most likely linking with libnsl (i.e. adding -lnsl to LDFLAGS) will
help (possibly throwing in -lsocket if -lnsl alone doesn't help).
