Running 32 bit SPARC on UltraSPARC

[John Klos <john%ziaspace.com@localhost>]

Just a note about the sparc64 kernel config files:

options        EXEC_ELF32      # Exec module for SunOS 5.x binaries.

EXEC_ELF32 is required to run 32 bit NetBSD SPARC binaries, too. I think 
the comment should reflect that.

Are there any issues running pkgsrc builds for SPARC on UltraSPARC? 
Anything I should look out for?

Thanks,
John
