In building librpclib.a on the PMAX, I need to do several things.

1. Changed Makefile to build and install librpclib.a

2. in clnt.h ,  I removed #ifdef _DCS_, #end _DCS

3. xdr_float.c --- says it can't be ported so just added section for #ifdef mips
similar to the one for the rt.

4. svc.c -- definition of svc_unregister was void in svc.c but bool_t in
svc.h so I changed it to bool_t in svc.c.

5.  getrpcent.c -- used the routine index ("strings.h"), which is the same as
strchr on some machines, so I changed it.
