[PATCH/RFA] Dejagnu: fix linker warning patters for NetBSD

[Jason Thorpe <thorpej at wasabisystems dot com>]

I finally got fed up with the following failures on NetBSD targets:

These tests fail because Dejagnu's prune_warnings function does not 
match the warnings emitted by more modern versions of NetBSD (it looks 
like the NetBSD patterns were written for the old NetBSD a.out 
toolchain).  The patch below fixes this.  If it is accepted here, I'll 
feed it upstream to the main Dejagnu maintainers, as well.

OK for mainline?  OK for 3.3 branch?

        * lib/target.exp (prune_warnings): Add two more linker
        warning patterns for warnings generated by modern verions
        of NetBSD.
