tcpdump/configure.in
guy 8f758e65ff Use AC_TRY_LINK, not AC_TRY_COMPILE, when looking for 
inet_ntop/inet_pton/inet_aton, and don't use AC_REPLACE_FUNCS to set
LIBOBJS to include the replacement module, as that does the full check
for the routine again, not just the simple replacement.

Move the tests in question after AC_LBL_LIBPCAP, so that we link with
the appropriate libraries (e.g., "-lsocket -lnsl" on Solaris) to use
when using those routines.
