The test for -lnsl, -linet, and -lsocket was only being run on IRIX, rather

Browse source 
than run everywhere except IRIX.  Rewritten to use AC_SEARCH_LIBS which
should avoid problems on IRIX and any other similar platform.

dnl The following three libraries (nsl,inet,socket) are needed on Sequent,
dnl and must be checked for in this order since each library depends on the
dnl preceding one.
