solaris archive_cmds change for sun CC c++ compiler

[Peter O'Gorman]

Hi,
On all versions of sun's compiler that I looked at, using c++ features (e.g. 
cout!) requires adding -lCstd -lCrun and -lc to the link line. This means 
that any library linking with -no-undefined fails to link properly with this 
compiler. I have added these libraries to the archive_cmds. While I was 
looking there, I saw an output_verbose_link_cmd that removes all the objects 
from the list, thus making it useless, so I removed the -nolib and set the 
output_verbose_link_cmd to 'echo'.

Okay for all branches? (having been suitably changed for 2.0/HEAD, of course).

Peter
