I agree that we should disallow non-PIC code in SPARC Solaris DSOs. 
This appears to be the purpose of '-z text' and I think we should use 
it.  Libtool is already working hard to avoid accidental use of 
non-PIC code in Solaris DSOs (even though Solaris can often deal with 
it).  Enforcing it is a good idea since use of this option is 
recommended.  Expect someone to complain when their software stops 
linking.

I agree that '-z defs' is the equivalent of no-undefined.  Using
'-z text' for this purpose is clearly wrong.
