lynx-dev more on configure wrt bind/resolv and inet_addr

[Henry Nelson]

"for cf_inetlib in -lbind -lresolv ; do ; if ; else ; done" will only
work if lresolv succeeds (which is highly unlikely if lbind succeeds).
A patch to the configure script to fix this is appended (dev.15).

It compiles okay on Solaris2.6, gcc2.8.1, slang1.2.2, but probably
will have no time to test the binary for a week or two.  Tested only
with a working libbind.a and no libresolv.

BTW, Tom, the test for socket in -lsocket is going to fail if people
get confused and define $LIBS with either -lresolv or -lbind before
running configure.
