Subject: Some makefile patches to stop the !#^%!& include files being touched

These were done from a very recent -current..  I got sick of the include 
files being touched, causing make to rebuild the entire system again.

Most of the makefiles were fixed, but these two slipped through:

src/lib/csu/i386/Makefile:  (stops <dlfcn.h> being touched)

  depend lint tags:

  depend lint tags:
  

And this one stops the rpc stuff being touched, causing the getpw* 
routines in libc to be rebuilt, hence causing just about everything to be 
rebuilt.

Note that these dont actually change anything... They just stop an 
identical file being installed over the top of an existing one for
No Good Reason(TM).  I just copied the style of tests from the other 
include makefiles.

It was not much fun to discover this on a 386SX-16... (now a 486, thank 
god! :-)

Cheers,
